The weight is per bag except on KLM and Air France, whose 12 kg is for the small bag and the cabin bag together. Wizz Air’s sizes leave out wheels and handles, which may add up to 5 cm.

How to read it
Carry-on limit: the bag’s length, width and height, as each airline prints them. American, Delta, United, Southwest, Alaska, JetBlue, Frontier, Allegiant, Hawaiian, Sun Country and Breeze count the wheels and handles. Outside the US, 8 of the 14 airlines here say their cabin bag size counts them, and Wizz Air leaves them out, though its wheels may add no more than 5 cm.
Total or weight: Delta, Alaska and Hawaiian also cap the three sides at 45 inches added together. Frontier, Sun Country and Breeze set a weight limit. The others give none on their carry-on pages.
Lowest fare: whether the cheapest economy ticket includes the carry-on. On United, Frontier, Allegiant, Sun Country, Breeze and Avelo, it doesn’t.
Measure your bag with a tape, wheels and handles included, and type the size into Will my bag fit? to see every airline’s answer at once.

Measure with the handle pushed down: from the floor to the top of the handle, then across the front and from back to front, wheels and pockets in.
Regional flights and full flights
On American Eagle regional flights, a carry-on bigger than the personal item size is valet checked at the gate, at no charge, except on Embraer 175 planes, which take carry-on bags. On Delta Connection flights (Delta names those with 50 seats or less), only personal items go on board; bigger bags get a pink Gate Claim/Planeside tag and ride in the hold. On CommutAir flights (United Express), only one personal item goes on board. Delta, United, Frontier and Sun Country say a carry-on can be checked at the gate when the bins are full.
