Last Updated: March 30, 2026

Southwest Airlines offers the most generous baggage policy in the United States—free carry-on, free personal item, AND two free checked bags. This unique combination means your carry-on strategy for Southwest differs significantly from other airlines. Whether you’re maximizing Southwest’s larger carry-on allowance (24″ x 16″ x 10″) or using their free checked bags while traveling light, this guide helps you find the best carry-on luggage Southwest travelers rely on.

Quick Answer: Best Carry-On for Southwest

Best overall: Standard 22″ x 14″ x 9″ carry-on (works on Southwest + all other airlines)

Best Southwest-specific: 24″ x 16″ x 10″ maximum-sized bag (only if you fly Southwest exclusively)

Southwest-Specific Packing Strategies

Strategy 1: Carry-On + 2 Free Checked Bags

The Southwest advantage: Most travelers overlook this strategy.

What to pack where:

Carry-on (keep with you):

Electronics (laptop, tablet, camera)
Medications and prescriptions
One change of clothes (in case checked bag delayed)
Travel documents and valuables
Entertainment for flight

Checked bag #1 (FREE):

Most clothing and shoes
Full-sized toiletries (no 3.4 oz TSA restrictions)
Bulky items (coat, boots)
Books and non-essential items

Checked bag #2 (FREE):

Sports equipment (golf clubs, skis)
Additional clothing for longer trips
Gifts or shopping items
Items you won’t need until destination

Benefits:
✓ No struggle lifting heavy carry-on
✓ Faster through security (lighter carry-on)
✓ More overhead bin space for others
✓ Avoid gate-checking risk
✓ Easier airport navigation

Strategy 2: Carry-On Only (Skip Free Checked Bags)

When this makes sense:

Short trips (3-4 days or less)
Business travel (minimal clothing needed)
Destinations with laundry access
Tight connections (no baggage claim wait)
Concern about lost luggage

Packing tips for Southwest carry-on only:

Use packing cubes to maximize space
Wear bulkiest items on plane (coat, boots)
Choose versatile clothing (mix and match)
Limit to 2 pairs of shoes
Travel-size toiletries (3.4 oz limit)
Roll clothes instead of folding

Southwest Boarding & Overhead Bin Strategy

Understanding Southwest’s Open Seating

Boarding order affects carry-on placement:

A1-A15 (EarlyBird or Business Select):

First to board
Prime overhead space directly above seat
Can bring full-sized carry-on without worry
Best strategy: Standard carry-on works perfectly

A16-A60:

Early boarding
Good overhead space availability
Minimal risk of gate checking
Strategy: Any carry-on size works

B1-B60:

Middle boarding group
Overhead space filling up
May need to place bag several rows away
Strategy: Consider checking bags (free anyway)

C1-C60:

Last to board
Limited overhead space
Higher gate-check risk (though free)
Strategy: Use 2 free checked bags, carry personal item only

EarlyBird Check-In Worth It?

Cost: $15-25 per person, per direction

Frequently Asked Questions

What size carry-on should I buy for Southwest?

For Southwest-only travelers, you can use up to 24″ x 16″ x 10″ carry-ons. However, most experts recommend standard 22″ x 14″ x 9″ bags that work on all airlines. Since Southwest offers two free checked bags, there’s little advantage to maximizing carry-on size—you can check larger items for free.

The sweet spot: A lightweight 22″ carry-on for essentials, plus take advantage of Southwest’s free checked bags for bulk items.

Should I take advantage of Southwest’s 2 free checked bags?

Yes, in most cases. Southwest’s free checked bag policy is unique among U.S. airlines. Checking bags allows you to:

Travel with full-sized toiletries (no 3.4 oz TSA limits)
Avoid carrying heavy bags through airports
Reduce overhead bin congestion
Travel more comfortably
Pack more items without weight concerns

Exception: Very short trips (1-3 days) or tight connections where baggage claim time is critical.

What’s the best luggage for Southwest’s boarding process?

For A group boarders (A1-A60): Any standard carry-on works perfectly—plenty of overhead space available.

For B group boarders: Standard 22″ carry-on, but consider using a checked bag instead since overhead space is limited.

For C group boarders: Personal item only + checked bags (free). Overhead space is very limited, and gate checking risks losing prime bin space.

Best overall strategy: Lightweight carry-on + utilize free checked bags.

Do I need hardshell or soft-sided luggage for Southwest?

Hardshell advantages:

Better protection (Southwest’s smooth operations mean less damage risk anyway)
Weather resistance
Scratch-resistant options
Modern aesthetic

Soft-sided advantages:

Lighter weight
Expandable (can add 2-3″ temporarily)
External pockets (easy access to essentials)
Fits better in tight overhead bins

For Southwest: Either works well. Since you can check bags free, choose based on what you’ll carry on (valuable items = hardshell, clothing = soft-sided).

How can I maximize Southwest’s baggage allowance?

Optimal Southwest packing strategy:

Carry-on bag (up to 24″ x 16″ x 10″): Electronics, medications, valuables, one change of clothes
Personal item (18.5″ x 8.5″ x 13.5″): Laptop, documents, entertainment, snacks
Checked bag #1 (FREE, 50 lbs): Main clothing, shoes, toiletries
Checked bag #2 (FREE, 50 lbs): Additional items, sports equipment, gifts

Total allowance: Up to 138 lbs of luggage for FREE (50+50+minimal carry-on weight), plus personal item.

This beats every other U.S. airline’s policy.

Is it worth buying Southwest-specific luggage?

Only if you fly Southwest exclusively (12+ times/year) AND never connect through other airlines.

Most travelers should buy: Standard 22″ x 14″ x 9″ carry-on
Southwest-only flyers could consider: 24″ x 16″ x 10″ maximum size

Reality: Since Southwest offers free checked bags, most travelers benefit more from universal-sized luggage and checking larger items rather than maximizing carry-on size.

Summary: Best Luggage Strategy for Southwest

For most Southwest travelers:

Standard 22″ x 14″ x 9″ carry-on (universal compatibility)
Lightweight construction (6-8 lbs empty)
TSA-approved locks
Smooth-rolling wheels
Quality brand (Away, Travelpro, Samsonite)

Take advantage of Southwest’s unique benefits:
✓ 2 free checked bags (pack heavy items)
✓ Free carry-on (keep valuables with you)
✓ Free personal item (maximize under-seat space)
✓ No change fees (flexible travel plans)
✓ Free gate checking (no penalty for oversized bags)

Bottom line: Southwest’s generous baggage policy means you can optimize for travel comfort rather than packing stress. Use a standard carry-on for essentials, check everything else for free, and enjoy the most luggage-friendly airline in America.
