Sizing it up. When airlines refer to âcarry-on luggageâ or âcarry-on baggage,â they mean the bag that meets size specifications to store it in the overhead bin. Trouble is, there is no such thing as a standard carry-on size. Every U.S. airline has its own rules. The big threeâAmerican, Delta, and United/U.S. Airwaysâhave settled on a uniform size (for now). Itâs 22 inches high x 9 inches deep x 14 inches wideâthese are external dimensions, including wheels and the handle. A few U.S. airlines are more generous with their carry-on size allowance, but some also impose weight restrictions and/or fees for carry-on baggage.
