Checked bag sizes: what the numbers actually mean
Luggage sizing terminology varies between brands and retailers in ways that create genuine confusion. Before the recommendations, it is worth establishing what the common size labels actually mean in practical terms so you can match the right bag to your actual trip lengths.
| Common label | Typical height | Typical capacity | Best suited to | Standard checked weight limit |
|---|---|---|---|---|
| Cabin / carry-on | 50–56cm | 30–45 litres | Weekend to 3-night trips | N/A — cabin bag |
| Medium / mid-size | 65–70cm | 60–80 litres | 1–2 week trips | 23kg |
| Large | 73–79cm | 85–110 litres | 2–4 week trips, family travel | 23kg |
| Extra large | 80cm+ | 110+ litres | Extended trips, relocation, equipment | Check airline |
The medium size — 65–70cm, 60–80 litres — is the most practical choice for the majority of travellers making trips of one to two weeks. It holds enough for a fortnight of efficiently packed clothing, fits within standard 23kg airline allowances with room to spare, and is manageable to manoeuvre when fully loaded through airports and hotels. Large bags become genuinely heavy and cumbersome when packed and can approach or exceed 23kg weight limits with dense packing. Extra-large bags exceed the 158cm linear dimension limit (height plus width plus depth) that most airlines apply to standard checked bags and may attract oversized surcharges.
The most common mistake in checked bag purchasing is buying a large bag for trips that a medium handles perfectly. A half-empty large bag wastes your checked weight allowance on the bag’s own empty weight and creates an unwieldy bag that is harder to navigate through airports.
Hardshell vs soft-shell checked bags: which is right for you
The choice between hardshell polycarbonate and soft-shell ballistic nylon is genuinely consequential for checked bags in ways that it is not for carry-ons. Here is an honest assessment of both.
The case for hardshell polycarbonate
Polycarbonate hardshell bags have clear practical advantages for checked luggage in most scenarios. They maintain their structural shape under the weight of other bags stacked on top in the hold. They provide rigid protection for fragile contents regardless of what happens during handling. They are waterproof by construction — rain on tarmac, condensation, or minor spillage cannot penetrate the shell. They resist the slashing that can compromise soft-sided bags at airports where luggage theft is reported. They are easier to clean after hold travel, which inevitably involves contact with conveyor belt residue, tarmac grime, and aircraft hold surfaces.
The polycarbonate advantage over ABS is significant for checked bags specifically: polycarbonate flexes under impact and recovers, while ABS transmits impact force rigidly and can develop stress cracks at corners and zip attachment points under repeated handling cycles. For bags used on more than four or five international trips per year, the durability difference between polycarbonate and ABS becomes clearly visible over a two to three year period.
The case for soft-shell ballistic nylon
Premium soft-shell checked bags from Briggs and Riley and Tumi have genuine advantages that polycarbonate cannot replicate. They expand to accept the occasional overpacked load that a rigid shell would refuse. They typically offer external pockets accessible without opening the main compartment — genuinely useful for items you need to access at the carousel. The best soft-shell bags (ballistic nylon construction) are highly abrasion-resistant and resist the scuffs and surface marks that accumulate on polycarbonate over time. Premium soft-shell brands back their bags with lifetime warranties that cover airline damage — an unusually strong commitment for bags that go into the hold.
For most travellers making standard holiday and business trips, polycarbonate hardshell is the correct choice. For intensive business travellers who value external pocket access, flexible expansion, and lifetime warranty coverage, premium soft-shell is worth the significant additional investment.
Best medium checked luggage 2026 (65–70cm)
1. Samsonite Proxis 67cm — Best medium checked bag overall
Dimensions: 69 × 46 × 27cm | Empty weight: 2.7kg | Capacity: 78 litres | Shell: Recycled polycarbonate | Price: £285–£350
The Samsonite Proxis in medium checked size is the most technically accomplished checked bag in this guide, and the strongest single recommendation for travellers who check bags regularly and want the best available specification. The combination of 2.7kg empty weight, 78 litres of capacity, recycled polycarbonate construction, and precision ball-bearing spinner wheels represents the current state of the art in medium checked luggage.
The 2.7kg empty weight is the figure that sets this bag apart from most of its competition. Standard-thickness polycarbonate medium checked bags from comparable brands typically weigh 3.2–3.8kg empty. The Proxis achieves 2.7kg through Samsonite’s material engineering — thicker-than-average recycled polycarbonate structured more efficiently — rather than through the thin-shell approach that IT Luggage uses to achieve similar weights. The result is a bag that is genuinely lighter without any compromise to structural performance, leaving 20.3kg of packing allowance within a 23kg airline limit.
Samsonite’s ball-bearing spinner wheels deserve specific attention in the context of checked luggage. At the 18–22kg loads that a fully packed medium checked bag generates, the quality of spinner wheels determines whether navigating a long airport terminal is comfortable or effortful. Cheap spinner wheels in this weight class bind, wobble, and drag. Samsonite’s precision ball-bearing wheels roll smoothly, quietly, and with consistent stability under the full range of realistic loaded weights — a quality difference that is immediately apparent compared to mid-range alternatives and that remains consistent over years of intensive use.
The interior Cross-Track system includes a full-width divider with compression straps on each side, a garment sleeve that protects suit jackets and formal wear from creasing, and integrated packing accessories. The TSA-approved combination lock is built into the zip for US and international travel. The recycled polycarbonate shell contributes meaningfully to Samsonite’s sustainability commitments without any compromise to the structural performance of the bag.
For frequent travellers who check bags on every trip — domestic or international — the Proxis justifies its premium price through the combination of payload efficiency (lighter means more packing allowance), wheel quality (better in-airport experience every time), and construction durability (a bag that will still be performing identically in five years of regular use).
Best for: Frequent checked bag travellers. International routes. Business trips of one to two weeks. Anyone who wants the best available specification in a medium checked bag and expects to get five or more years of regular use from it.
Limitation: Premium price. 78 litres covers up to two weeks comfortably — not sufficient for very long trips without additional luggage.
2. Antler Clifton 67cm — Best British brand medium checked bag
Dimensions: 67 × 45 × 27cm | Empty weight: 3.2kg | Capacity: 70 litres | Shell: Polycarbonate | Price: £200–£255
Antler’s polycarbonate Clifton in medium checked size occupies the sweet spot between American Tourister’s accessible price and Samsonite’s premium engineering: notably better wheel quality and construction finish than American Tourister, at a price meaningfully below the Samsonite Proxis. For UK-based travellers who want genuine premium quality from a long-established British brand without paying Samsonite’s full premium, the Clifton is the correct choice.
The full-thickness polycarbonate shell handles the stresses of checked bag travel with appropriate durability for a bag used four to eight times per year on international routes. The dual-spinner wheels are smooth, quiet, and stable under load — not quite at Samsonite’s precision ball-bearing standard, but noticeably superior to budget and mid-range alternatives. The telescoping handle operates through four height settings with firm, wobble-free locking at each position.
At 3.2kg empty it leaves 19.8kg of packing allowance within a 23kg limit — 0.5kg less than the Proxis, which for most leisure travellers is an entirely irrelevant distinction. The 70-litre capacity handles two weeks of efficiently packed holiday clothing without requiring unusual discipline. The interior uses a full-width divider with compression straps and a mesh organisation pocket. The TSA-approved combination lock is integrated. The wide range of colours and distinctive two-tone options make it one of the most visually recognisable bags on an airport carousel.
Antler backs the Clifton range with a two-year guarantee against manufacturing defects, with a brand reputation for customer service that has been established over decades in the UK market.
Best for: UK travellers who want premium polycarbonate quality at a below-Samsonite price. Holiday travel of up to two weeks. International leisure routes.
Limitation: 3.2kg empty weight is heavier than the Proxis by 0.5kg. 70-litre capacity is appropriate for two weeks but leaves less headroom than the Proxis’s 78 litres.
3. American Tourister Airconic 67cm — Best value polycarbonate medium checked bag
Dimensions: 67 × 46 × 27cm | Empty weight: 2.9kg | Capacity: 72 litres | Shell: Polycarbonate | Price: £100–£140
American Tourister applies Samsonite-level engineering standards to wheel and handle components across its entire range, which is what makes the Airconic an exceptional value proposition at under £140. The polycarbonate shell is full-quality — not the thin-shell compromise of budget lightweight brands — and the 2.9kg empty weight is competitive with bags costing twice as much. The Samsonite-derived wheel quality shows up in performance that is noticeably smoother and more consistent under load than equivalent-priced bags from other budget-to-mid-range brands.
The 72-litre capacity is practical for two-week holiday trips and the 2.9kg empty weight leaves 20.1kg for contents within a 23kg limit. The TSA-approved combination lock is built in. The interior is straightforward — compression straps, a divider panel, and basic organisation pockets — which is all that most checked bag users need in practice.
For families equipping multiple travellers simultaneously, the American Tourister Airconic makes a polycarbonate set genuinely affordable. Buying two Airconic 67cm bags for a couple costs £200–£280. Buying two Antler Clifton 67cm bags costs £400–£510. Buying two Samsonite Proxis 67cm bags costs £570–£700. The Airconic delivers approximately 80% of the Proxis’s functional performance at approximately 35% of its price — a compelling value equation for leisure travellers who are not pushing their bags to the absolute performance ceiling.
Best for: Regular holiday travellers. Families who need multiple matching bags simultaneously. Those who want polycarbonate quality under £140.
Limitation: Wheels less refined at very heavy loads compared to Antler and Samsonite. Basic interior organisation only.
4. Rimowa Essential Check-In M — Best premium medium checked bag
Dimensions: 69.5 × 49.5 × 28.5cm | Empty weight: 3.6kg | Capacity: 75 litres | Shell: Polycarbonate | Price: £490–£560
Rimowa’s Essential Check-In M is one of the most recognised pieces of travel luggage in the world and its reputation is genuinely earned through engineering quality rather than marketing alone. The parallel-grooved polycarbonate shell is both the brand’s visual signature and a structural innovation: the grooves add rigidity through geometry rather than through additional material, producing a shell that is more rigid than equivalent smooth-walled designs at the same weight. This is sophisticated engineering that most luggage brands do not attempt.
The multi-wheel system sets Rimowa apart most distinctively from all other checked bags: eight wheels arranged in four dual-wheel clusters that maintain smooth, stable rolling even at the full 20–22kg weights of a heavily packed checked bag on varied surfaces. Standard four-spinner bags develop a wobble and drag under heavy load on surface transitions. Rimowa’s eight-wheel system handles these transitions with consistency. For frequent travellers who navigate long international terminals regularly with fully-packed checked bags, this is a daily quality of life difference that becomes very apparent compared to any other checked bag.
The TSA-approved combination lock uses Rimowa’s distinctive mechanism integrated into the polycarbonate shell itself rather than the zip — more secure and more elegant than zip-mounted locks. The interior cross-strap compression system is quality-lined and protects clothing better than most competitors. The telescoping handle is constructed to commercial travel standards that will not loosen or develop wobble through years of intensive use.
Rimowa’s global service and repair network is the most extensive in the luggage industry — bags can be professionally repaired at Rimowa stores or service centres in most major international cities, which matters specifically for bags used on international routes where damage can occur far from home.
The cost-per-trip calculation over a ten-year ownership period brings the premium price into better perspective. At five trips per year over ten years, £490–£560 equates to £9.80–£11.20 per trip. A £120 ABS bag replaced every three years under similar use costs approximately the same over the same period, with substantially less performance throughout.
Best for: Premium international travel. Frequent checked bag travellers who want the definitive quality purchase. Anyone who values the global service network and the engineering standard that makes this bag last a decade of intensive use.
Limitation: Very premium price. 3.6kg empty weight is not the lightest in class. Significant investment to justify for infrequent travellers.
5. IT Luggage World’s Lightest 67cm — Best lightweight budget medium checked bag
Dimensions: 69 × 47 × 29cm | Empty weight: 2.2kg | Capacity: 80 litres | Shell: Polycarbonate | Price: £75–£100
For travellers whose primary goal in a medium checked bag is maximising the packing payload available within a 23kg airline allowance, the IT Luggage World’s Lightest delivers the best weight-to-price ratio available. At 2.2kg for a polycarbonate medium checked bag under £100, it leaves 20.8kg for contents within a standard 23kg limit — the highest payload figure in this entire guide for a medium checked bag.
The thin polycarbonate shell achieves this weight by being significantly thinner than standard bags. Polycarbonate retains its fundamental crack-resistant property at reduced thickness, but the structural rigidity and crush resistance reduce proportionally. For standard travel contents — clothing, shoes, toiletries, and accessories — this makes no practical difference. For fragile items packed without additional padding directly against the shell walls, a thicker shell provides better protection.
The 80-litre capacity is the highest in this section and generous for a medium-size bag. Wheels and handle are functional rather than premium. IT Luggage provides a 10-year guarantee. For the traveller who checks bags occasionally and wants polycarbonate quality at under £100 with maximum payload, this is the most effective option at this price.
Best for: Budget-conscious travellers who want maximum payload in a polycarbonate medium checked bag. Occasional checked bag users for whom lightness matters more than premium construction.
Limitation: Thin polycarbonate shell. Functional wheels and handle quality only.
6. Briggs and Riley Baseline Large Expandable — Best premium soft-shell checked bag
Dimensions: 70 × 47 × 37cm (expanded) | Empty weight: 4.1kg | Capacity: 83 litres (expanded) | Material: Ballistic nylon | Price: £520–£600
Briggs and Riley’s Baseline in checked bag size is the definitive premium soft-shell checked luggage for intensive travel use. The unconditional lifetime guarantee — covering all damage including airline damage, without receipts, registration, or questions — transforms this from an expensive checked bag into a lifetime purchase that Briggs and Riley honours with full repair or replacement regardless of the cause or age of the damage.
The ballistic nylon exterior resists the abrasion, cuts, and stress that soft-sided bags accumulate during checked bag handling. Standard polyester and nylon exteriors show fraying, thinning, and surface damage over years of hold travel. Ballistic nylon — the same material used in body armour and military equipment — maintains its integrity through conditions that degrade standard fabric.
The compression and expansion system is the feature that most distinguishes this bag in practical use: an external compression strap simultaneously locks the bag and reduces its profile when packing lightly, and expands to accept significantly more volume when the trip demands it. This flexibility means the bag works equally well for a three-day business trip and a two-week holiday without the dead space and structural inefficiency of a bag that is half-empty on shorter trips.
Two large exterior zip pockets provide quick access to items at the carousel and during airport navigation — a feature that hardshell bags cannot offer without compromising the shell’s structural integrity. The interior organisation system includes dedicated compartments, compression panels, and a quality lining that protects clothing better than most competitors.
At 4.1kg the empty weight is the heaviest in this guide, leaving 18.9kg of packing allowance within 23kg. For a bag used primarily on full-service airlines where the soft-shell and expansion features deliver most of their value, this weight trade-off is reasonable.
Best for: Intensive business travel. Frequent checked bag travellers who prioritise external access, flexible expansion, and a lifetime warranty above all other factors.
Limitation: 4.1kg empty weight is the heaviest in this guide. Very premium price. No rigid shell protection for fragile contents.
Best large checked luggage 2026 (73–79cm)
7. Samsonite Proxis 77cm — Best large checked bag overall
Dimensions: 77 × 53 × 30cm | Empty weight: 3.2kg | Capacity: 107 litres | Shell: Recycled polycarbonate | Price: £320–£390
The Samsonite Proxis in large size applies the same engineering philosophy as the medium version — lightweight recycled polycarbonate, precision ball-bearing wheels, maximum internal volume — to the largest standard checked bag format. At 3.2kg for 107 litres it is remarkably light for its class. Most large checked bags weigh 4.0–5.5kg empty; the Proxis’s 3.2kg leaves 19.8kg for contents within a 23kg limit, which for a three-week trip with efficient packing provides genuine headroom for clothing plus items purchased abroad.
The ball-bearing wheel quality matters more on a large bag than a medium one. At the 18–23kg weights that a fully packed large bag generates, wheel quality determines whether navigating a large international terminal is physically demanding or comfortable. Samsonite’s precision wheels under this weight class are the best available for sustained smooth rolling under maximum load. The telescoping handle is wide-set and solid, providing good leverage for a heavily loaded tall bag.
The 107-litre interior uses the Cross-Track organisation system with compression straps on both sides, a garment sleeve, and integrated packing accessories — well-suited to the extended and varied packing requirements of multi-week trips. The TSA-approved combination lock is built in.
Best for: Extended trips of two to four weeks. Family travel consolidating packing into a single large bag. Itineraries requiring maximum volume within a quality construction.
Limitation: Premium price. Large bags require a full 23kg allowance to be used effectively — always confirm your airline’s specific limit before packing to capacity.
8. American Tourister Airconic 77cm — Best value large checked bag
Dimensions: 77 × 52 × 31cm | Empty weight: 4.0kg | Capacity: 99 litres | Shell: Polycarbonate | Price: £120–£160
The American Tourister Airconic in large size extends the brand’s value proposition to the largest standard checked format: 99 litres of polycarbonate capacity at a price under £160. For families who need a large bag two or three times per year — the annual summer holiday, the Christmas family visit, the two-week all-inclusive — the Airconic makes polycarbonate quality accessible without a premium investment.
The 4.0kg empty weight is standard for a large polycarbonate bag, leaving 19kg within a 23kg limit — workable for three weeks of efficient packing. The Samsonite-heritage wheel quality shows in consistent rolling performance on airport surfaces under the heavy loads a large bag generates when fully packed. The TSA-approved combination lock, full-length divider, and compression straps complete a bag that delivers everything a large checked bag needs to do at a fraction of premium brand pricing.
Buying the Airconic in carry-on, medium, and large sizes creates a complete polycarbonate matching set for approximately £300–£400 total — a fraction of the equivalent Samsonite or Antler set cost.
Best for: Holiday travel requiring a large checked bag. Families. Those who want polycarbonate quality in a large format without a premium investment.
Limitation: 4.0kg empty weight. Wheels less refined under maximum load compared to Samsonite. Basic interior.
9. Roncato Zero Gravity 77cm — Lightest large checked bag
Dimensions: 77 × 53 × 29cm | Empty weight: 3.1kg | Capacity: 110 litres | Shell: Polypropylene | Price: £160–£200
Roncato’s Zero Gravity applies the same lightweight Italian engineering used in their carry-on range to the large checked format, and the result at the extreme end of the weight spectrum is genuinely impressive: 3.1kg for a 110-litre bag. In this size class, that is the lightest standard large suitcase in widespread availability. The comparison to typical large bags in the same class is stark — saving 1–2kg of empty bag weight at this size translates directly to an extra outfit, a pair of shoes, or souvenir capacity on the return journey.
Polypropylene at this size carries the same caveat as at carry-on scale: it is lighter than polycarbonate and adequate for normal checked bag travel, but marginally less crack-resistant under the heaviest baggage handling impacts. For large bags that will primarily see standard airport handling rather than extreme conditions, the polypropylene performance is sufficient and the weight saving is real. The Italian spinner wheels are smooth and stable even at the heavy loads a 110-litre bag generates. The butterfly-opening interior uses full-width compression straps throughout.
Best for: Extended trips where maximising packing payload in a large bag is the priority. Long-haul travellers with generous checked allowances who want minimum empty bag weight.
Limitation: Polypropylene marginally less crack-resistant than polycarbonate under heavy baggage handling impacts.
10. IT Luggage World’s Lightest 77cm — Best budget large checked bag
Dimensions: 79 × 55 × 31cm | Empty weight: 2.8kg | Capacity: 109 litres | Shell: Polycarbonate | Price: £85–£115
IT Luggage’s large-format World’s Lightest applies the same ultra-thin polycarbonate approach to the largest standard checked size. At 2.8kg for a 109-litre bag it is technically the lightest large checked bag in this guide, edging the Roncato Zero Gravity (3.1kg) by 300 grams through the thin-shell engineering. Within a 23kg limit, 2.8kg empty leaves 20.2kg for contents — the highest payload figure for any large bag in this guide.
The familiar thin-shell caveat applies: the polycarbonate offers crack resistance at this thickness but reduced structural rigidity compared to standard-thickness shells. For extended trips where the bag will be checked on multiple consecutive legs, a thicker-shelled bag offers marginally better long-term structural integrity. For occasional large bag users making two or three extended trips per year, the IT Luggage is entirely adequate and represents exceptional value for the payload advantage it provides.
Best for: Extended trip travellers who want maximum packing payload in a large bag at minimum cost. Budget buyers who need polycarbonate at this size.
Limitation: Thin polycarbonate shell. Functional rather than premium wheels and handle.

Checked bag airline allowances: what you can actually take
Understanding your airline’s checked bag allowance before you pack is essential. The variation between carriers is significant — from budget airlines that charge per kilo for checked bags added at the gate, to full-service carriers that include 23–30kg as standard. The table below covers current allowances for the most commonly used carriers by UK travellers.
| Airline | Checked bag allowance (Economy) | First bag fee | Excess weight charge | Notes |
|---|---|---|---|---|
| British Airways | 23kg × 1 bag | Included | ~£65 per excess bag | Both carry-on and checked included on most fares |
| Jet2 | 22kg × 1 bag | Included | ~£12/kg over limit | Both carry-on and checked bag included |
| EasyJet | 23kg × 1 bag | £26–£55 by route and timing | ~£12/kg over limit | Must be pre-booked; gate price significantly higher |
| Ryanair | 20kg × 1 bag | £25–£50 by route | ~£11/kg over limit | Lower 20kg limit than most; pre-book for best price |
| Wizz Air | 20–32kg by allowance | £22–£50 by route | ~£12/kg over limit | Allowance varies significantly by fare and route |
| Lufthansa | 23kg × 1 bag | Included Economy | ~£70 per excess kg | Included on Economy and above |
| Emirates | 23–35kg by route | Included | ~£50–£150 per excess kg | More generous allowance on some long-haul routes |
| Singapore Airlines | 30kg Economy | Included | ~$100 per excess kg | Among the most generous standard allowances |
| Delta | 23kg × 1 bag | $35 first bag | $100–$200 per extra bag | First bag fee applies on most Economy fares |
| United | 23kg × 1 bag | $35 first bag | $100–$200 per extra bag | First bag fee applies on most Economy fares |
Always check your specific airline’s current baggage policy before travel. Rules vary by route, fare class, and booking channel — the rates above are approximate and subject to change. Pre-booking checked bags in advance is almost always significantly cheaper than paying at the airport or gate.
How to protect your checked bags and avoid damage claims
Checked bags face handling conditions outside your control, but several practical steps meaningfully reduce the risk of damage and improve your position if damage occurs.
Choose polycarbonate over ABS for checked bags
This is the most impactful preventive step. Polycarbonate flexes under impact rather than cracking, which makes it significantly more resilient under the repeated stresses of baggage handling. ABS bags that survive their first two or three trips without issue can develop stress fractures at corners and zip attachment points as impact stress accumulates. For bags checked more than five or six times per year, the durability difference between polycarbonate and ABS is clearly visible over a two to three year ownership period.
Use TSA-approved locks on US-bound travel
Any checked bag travelling to or through the United States should be secured with a TSA-approved combination lock. US Customs and Border Protection may open checked bags for inspection. Non-TSA locks will be cut off and not replaced. TSA-approved locks are opened with a master key carried by CBP staff and relocked after inspection. All premium luggage brands include TSA locks as standard on all bags in their range.
Label inside and outside
Attach a durable luggage tag with your name, mobile number, and email to the exterior of every checked bag. Place an identical identification slip inside the bag, visible through any interior mesh panel. If the external tag is removed during handling — this happens more often than you might expect — the internal label is what allows the bag to be returned to you when it arrives at a lost luggage desk.
Photograph your bags before check-in
Take a clear, timestamped photograph of each checked bag immediately before handing it over at check-in, showing the bag’s condition at that moment. If you discover damage at the baggage carousel, this photograph is your most useful piece of evidence for an airline damage claim. Report damage immediately at the airport before leaving the baggage claim area — most airlines require on-site reporting for claims to be valid — and complete a Property Irregularity Report (PIR) with the baggage desk before you leave the terminal.
Wrap fragile items in clothing
The most effective protection for fragile items in checked bags is not a better shell — it is positioning and padding within the bag. Fragile items packed directly against the shell wall receive the full force of any impact transmitted through that wall. The same items wrapped in rolled clothing, positioned in the centre of the bag, and surrounded by soft items on all sides receive dramatically less impact force. A polycarbonate shell provides the outer protection layer; clothing and packing organisation provides the inner protection layer.
Checked bag maintenance: making your suitcase last
A well-maintained checked bag lasts significantly longer than one that is stored and used without care. The three components that degrade fastest — wheels, zips, and telescoping handles — are all maintainable with minimal effort and cost.
Spinner wheels: After every trip, remove hair, grit, and debris from the wheel channel grooves using a small brush or toothpick. This accumulated debris is the primary cause of progressive wheel roughness and noise. On medium and large checked bags where wheels carry significant loads, occasional application of a small amount of silicone spray to wheel axles maintains smooth rotation. Avoid oil-based lubricants which attract additional debris.
Zips: Apply a wax-based zip lubricant — a plain candle works perfectly — along the coil teeth of all zip coils every few months. Thirty seconds of maintenance extends zip life through thousands of additional cycles. Never force a stiff zip; that is how coils crack at stress points. If a zip begins binding consistently, lubrication should be applied immediately before the binding causes coil damage.
Telescoping handles: Clean the telescoping mechanism channels with a dry cloth to remove grit and sand that accumulates inside the housing. On bags stored between trips, extend the handle slightly rather than leaving it fully retracted — full retraction over extended periods can cause the internal mechanism to seize. If the handle develops wobble, a small amount of lubricant applied to the mechanism shaft (not the outer housing) can restore firmness.
Polycarbonate shell care: Clean polycarbonate shells with mild soap and warm water on a soft cloth. Avoid bleach, acetone, or abrasive cleaners — these can compromise the surface treatment and in some cases affect the structural properties of the polycarbonate. Minor scuffs and surface marks are unavoidable and most experienced travellers accept them as the natural record of a well-used bag.
Storage: Store checked bags upright with the telescoping handle partially extended. Avoid storing heavy items inside bags during extended periods of non-use — sustained internal pressure can distort the frame geometry over months of storage. For long storage periods, a dust bag or cover keeps the exterior clean and protects the shell surface.
Frequently asked questions about checked luggage
What is the best checked suitcase size for most travellers?
For most travellers making trips of one to two weeks, a medium checked bag of 67–69cm and 70–80 litres is the most practical single purchase. It holds two weeks of efficiently packed clothing within a 23kg allowance, is manageable to manoeuvre when fully packed, and avoids the wasted space and unwieldy handling of an oversized large bag on shorter trips. Large bags (75–79cm) are genuinely useful only for trips of three weeks or more, family travel consolidating multiple people’s packing, or itineraries where the destination requires significant equipment.
Is it better to buy polycarbonate or ABS checked luggage?
Polycarbonate is the strongly preferred choice for checked luggage for the specific reason that it flexes under impact rather than cracking. Checked bags receive repeated impacts through baggage handling that carry-on bags do not experience, and the cumulative effect of that impact stress on ABS bags over years of use is clearly visible in the stress fractures that develop at corners and zip stress points. If polycarbonate is available at your budget — and it is, from American Tourister and IT Luggage at under £140 — it is always worth choosing over ABS.
How do I avoid paying overweight checked bag charges?
The most effective approach combines choosing a lightweight bag (fewer kilograms of empty bag weight means more packing allowance within the limit) with disciplined packing. A 2.7kg medium bag leaves 20.3kg for contents within 23kg; a 3.8kg bag leaves only 19.2kg. Always weigh your packed bag at home before leaving for the airport — a luggage scale costs £8–£15 and removes all uncertainty. Pre-booking checked bags online in advance is significantly cheaper than paying at the airport or gate on every major airline.

What is the 158cm linear rule for checked luggage?
Most airlines apply a maximum linear dimension limit of 158cm (total of height plus width plus depth) for standard checked bags beyond which oversized surcharges apply. A standard large suitcase of 77 × 53 × 30cm measures 160cm linear — right at the boundary — so check your specific bag’s total dimensions against your airline’s policy if you are purchasing a large bag. Medium bags at 67–69cm typically measure 130–145cm linear, well within standard limits. Extra-large bags above 80cm frequently exceed the 158cm limit.
How often should I replace my checked luggage?
There is no fixed interval — the correct replacement trigger is when the bag’s performance has noticeably degraded rather than at a set time period. The most common signs that a checked bag needs replacing: spinner wheels that have become rough, inconsistent, or difficult to roll under load and cannot be repaired; shell cracks at corners, zip attachment points, or handle housing that compromise structural integrity; zip coils that bind, split, or fail to close fully despite lubrication; telescoping handle that has developed permanent wobble or fails to lock reliably. For polycarbonate bags used four to six times per year, ten or more years of service is realistic with appropriate maintenance. For ABS bags under similar use, three to five years is more typical before structural fatigue becomes noticeable.
What is the maximum weight I can put in a checked bag?
Most airlines apply a 23kg limit per checked bag in economy class on standard fares, with some long-haul carriers allowing 25–32kg. The practical maximum is set by two factors: the airline limit (which attracts significant excess weight charges if exceeded) and the physical capacity of the bag. A medium 70–78 litre bag packed with clothing, shoes, and toiletries typically reaches 15–20kg before hitting volume limits. A large 99–110 litre bag can easily reach 23kg or more when fully packed with dense items. Always weigh before travel rather than estimating — the consequences of an overweight bag at the airport are financially disproportionate to the small cost of a luggage scale at home.
What is the best way to fit more into a checked bag?
The most effective techniques: use compression packing cubes to reduce the volume of soft clothing items by 30–40%; roll clothing rather than folding to use the internal geometry of the bag more efficiently, particularly in corners and along the edges; pack shoes with socks and small items stuffed inside them rather than leaving them empty; place heavy items (shoes, toiletries) at the base of the bag near the wheel housing rather than at the top; and use every available space including the interior of shoes, the space around toiletry bags, and the perimeter edges where flat-folded items do not reach.

Our verdict on the best checked luggage 2026
For a medium checked bag used regularly on domestic and international routes, the Samsonite Proxis 67cm is the outstanding recommendation. The 2.7kg empty weight, 78-litre capacity, recycled polycarbonate construction, and precision ball-bearing wheels represent the best available combination of payload efficiency, durability, and in-airport performance at this size. For UK travellers who want premium quality at a below-Samsonite price, the Antler Clifton 67cm is the standout British brand alternative. For those who need polycarbonate quality within a tight budget, the American Tourister Airconic 67cm at under £140 delivers the best value in the category.
For the premium buyer who wants the definitive investment in checked luggage that will last a decade of intensive international travel, the Rimowa Essential Check-In M is the engineering and quality benchmark, backed by the most extensive global service network in the luggage industry. For intensive business travel with a preference for soft-shell flexibility and lifetime warranty coverage, the Briggs and Riley Baseline is the professional standard.
For large checked bags, the Samsonite Proxis 77cm leads on quality and payload efficiency. The American Tourister Airconic 77cm is the value recommendation for occasional large-bag use, and the Roncato Zero Gravity 77cm is the choice for travellers who want the maximum packing payload in a large bag through the lightest possible empty weight.
Before any purchase, verify your checked bag’s dimensions against the linear dimension limit (158cm) and confirm your airline’s specific weight allowance for your fare class — both details are essential inputs to choosing the right size.
