Roller meets INTERNATIONAL and USA domestic carry-on size requirements. Although passengers are rarely asked to put their roller into airline test "frames", photographers can travel with the peace of mind knowing that this roller is designed to fit. Shown is an AIR CANADA luggage test frame. The Airport International V2.0 has also been tested in BRITISH AIRWAYS, KLM, UNITED, and other major airlines' test frames. Actually, the most important feature is that this roller "looks" small and is visually within legal carry-on requirements. It does not call out to be questioned by airline attendants on major flights.
