Airline Baggage Size & Weight Limits (2026 Guide) – Carry-On & Checked Bag Rules Explained
Complete comparison of airline baggage rules for 2026: exact carry-on dimensions, personal item sizes, checked bag weight limits, and fees for major US, European, and international airlines. Avoid unexpected fees with our authoritative guide.
Why Baggage Rules Differ by Airline
Airline baggage policies vary significantly based on business model, route profitability, aircraft type, and competitive positioning. Budget carriers like Spirit and Ryanair charge for nearly everything to keep base fares low, while full-service airlines like Delta and Emirates include more generous allowances. International routes typically offer better baggage allowances than domestic flights due to longer travel distances and passenger expectations.
Baggage fees change frequently as airlines adjust pricing strategies. What was free last year might cost $35 today. This guide simplifies comparison by providing side-by-side tables of current 2026 policies, helping you avoid unexpected fees and pack smarter for your next trip.

Carry-On Baggage Size & Weight Limits
Standard Carry-On Size
Most major U.S. airlines allow carry-on bags up to 22 x 14 x 9 inches (56 x 36 x 23 cm), including handles and wheels. This measurement represents the maximum external dimensions your bag can have to fit in the overhead bin.
How to Measure Your Carry-On Correctly
- 1Include everything:
Measure the bag with handles, wheels, and any external pockets fully extended.
- 2Use a tape measure:
Measure length (longest side), width (front to back), and height (top to bottom including wheels).
- 3Check linear inches:
Add all three dimensions together. For carry-ons, this should not exceed 45 linear inches (22+14+9).
- 4Test the fit:
If possible, test your bag in the airline's sizing bin at the airport before your trip.

International vs Domestic Baggage Differences
Domestic Flights (U.S.)
- Weight limit: 50 lbs per bag (economy)
- Size limit: 62 linear inches
- Free bags: Usually 0 (except Southwest)
- First bag fee: $35-$45 (online)
- Overweight fee: $100 for 51-70 lbs
International Flights
- Weight limit: 50 lbs (economy), 70 lbs (business/first)
- Size limit: 62 linear inches (same as domestic)
- Free bags: Usually 1-2 bags (economy)
- Piece concept: Number of bags matters more than total weight
- Premium cabins: Higher weight allowances and more free bags
Understanding the "Piece Concept"
International flights typically use the "piece concept" where you're allowed a certain number of bags (usually 1-2 for economy, 2-3 for business/first class), each with its own weight limit. This differs from some international carriers that use a total weight allowance system where you can distribute weight across multiple bags as long as the total doesn't exceed the limit.
