Airline baggage policies are the most confusing part of travel planning. Every airline has different rules for carry-on size, personal item allowance, and baggage fees. What’s allowed on Ryanair might get you charged on Spirit Airlines. What fits in the overhead bin on one airline might be too large for another.
Understanding airline baggage rules before you book is essential. It prevents surprise fees at the airport, reduces stress during check-in, and helps you pack strategically. This comprehensive guide covers baggage policies for 50+ airlines, from budget carriers like Spirit and Ryanair to full-service airlines like American and United.
Whether you’re flying domestically or internationally, budget or premium, this resource explains exactly what you can bring, how much it costs, and how to avoid overage fees. We update this guide regularly as airline policies change, so you always have current information.
Why Airline Baggage Rules Matter
Airline baggage fees generate billions in revenue annually. In 2025, the average checked baggage fee was $30-$35 per bag, and overweight fees ranged from $50-$150. For a family of four, unexpected baggage fees can add $200-$400 to your travel cost.
Beyond cost, understanding baggage rules affects how you pack and travel. Knowing your airline’s carry-on size limit (typically 22 x 14 x 9 inches for most carriers) helps you choose appropriate luggage. Knowing personal item policies (usually 18 x 14 x 8 inches) determines whether you can bring a backpack or underseat bag.
Budget airlines enforce baggage policies more strictly than full-service carriers. Spirit Airlines, for example, charges $35-$50 for carry-on bags that don’t fit their strict 18 x 14 x 8 inch personal item limit. Ryanair charges €10-€20 for oversized carry-ons. These fees add up quickly if you fly frequently.
International flights have different baggage allowances than domestic flights. Transatlantic flights typically allow 2 checked bags plus a carry-on, while European budget airlines often include only a personal item in the base fare. Understanding these differences prevents costly surprises.
The key to stress-free travel is knowing your airline’s specific baggage policy before you arrive at the airport. This guide provides that information for 50+ airlines, organized by carrier and flight type.

Key Concepts: Understanding Airline Baggage
Carry-On Luggage vs. Personal Item
Most airlines allow both a carry-on bag and a personal item. The carry-on is typically 22 x 14 x 9 inches (56 x 45 x 25 cm) and weighs up to 50 lbs. The personal item is smaller, usually 18 x 14 x 8 inches (45 x 35 x 20 cm), and can be a backpack, purse, or underseat bag. Budget airlines often charge for carry-ons but allow one free personal item.
Checked Baggage Allowance
Full-service airlines typically include 1-2 free checked bags (50 lbs each) with most fares. Budget airlines charge $25-$50 per checked bag. International flights often allow 2 checked bags, while domestic flights may limit you to 1. Premium cabin passengers receive higher allowances.
Weight Limits
Carry-on bags must typically weigh under 50 lbs. Checked bags have the same limit, though some airlines charge for bags over 70 lbs. Budget airlines enforce weight limits strictly; full-service airlines are often more lenient.
Oversized Baggage Fees
Bags exceeding size or weight limits incur fees: typically $50-$150 for oversized carry-ons, $50-$200 for overweight checked bags, and $100-$300 for extra-large items like sports equipment.
Frequently Asked Questions
Q: What’s the standard carry-on size for airlines?
A: Most airlines allow carry-on bags measuring 22 x 14 x 9 inches (56 x 45 x 25 cm). However, budget airlines like Spirit (18 x 14 x 8 inches) and Ryanair (22 x 18 x 10 cm) have stricter limits. Always check your specific airline’s policy before purchasing luggage.
Q: Can I bring a backpack as a carry-on?
A: Yes, as long as it meets your airline’s size requirements. Many travelers use backpacks as personal items (typically allowed free) or as carry-ons if they fit the size limit. Soft-sided backpacks compress better than hard-sided luggage, making them ideal for tight overhead bins.
Q: How much does it cost to check a bag?
A: Full-service airlines typically include 1-2 free checked bags. Budget airlines charge $25-$50 per bag. Some airlines charge more for the first bag ($35) than the second ($50). Premium cabin passengers often get free checked bags regardless of airline.
Q: What happens if my luggage is overweight?
A: Overweight fees range from $50-$200 depending on how much over the limit your bag is. Some airlines charge per pound over the limit. Weigh your luggage at home before heading to the airport to avoid surprises.
Q: Are international flight baggage allowances different?
A: Yes. Transatlantic flights typically allow 2 checked bags plus a carry-on. European budget airlines often include only a personal item in the base fare. Always check your specific airline’s international baggage policy.
