Have a specific airline in mind?

If you've got a trip coming up (or a frequent flier status to maintain), use the chart below to see which carry-on will fit on your flights. We tested our carry-ons at JFK, EWR, and LGA to see how each size fits on the below airlines. Learn more about our process.

Keep in mind that this info can change at any time, but don't worry; we'll do our best to keep it up to date. You'll also want to check the airline that's operating the flight, which may be different from the airline you booked with.

This information is accurate as of November 2025. The results here reflect our findings using empty suitcases in the sizers at JFK, EWR, and LGA, but note that the sizers used at your airport may be different. Also, any airline can still make you gate check your bag if overhead space is full—but every trip has its surprises.

*This chart accounts for all styles of our Carry-On and Bigger Carry-On sizes, including Softside, Aluminum, Aluminum Edge, and Flex (not expanded).

**These airlines were not verified by our testing in 2025 due to sizers not being available at the airports we visited. The information is accurate based on customer reports, partner airline sizers, and information provided by the airlines.

Please take special note that The Carry-On Aluminum Edge did not fit the sizers for Air Canada and the Bigger Carry-On Aluminum Edge did not fit the sizers for United, Porter Air, and WestJet.
