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, LHR, and LGW to see how each size fits on the below airlines.

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.
