Carry-on size by airline
19 airlines, each with its official carry-on and personal-item allowance and a built-in fit checker. Every size is traced to the airline's own page and dated.
American Airlines
22 x 14 x 9 with wheels and handles. Most bags sold as carry-ons fail it; see which ones pass.
Southwest
24 x 16 x 10, the roomiest box of any major US airline. Almost everything fits; nine bags still fail.
United
22 x 14 x 9, but domestic Basic Economy only gets a 17 x 10 x 9 personal item. The fare is the rule.
