Sizes are compared longest-side-first, so a bag counts as fitting if it fits in any orientation — the same way an airport sizer works. Weight is a separate limit and is not considered here; the airline pages carry it.
On 4 of the 30 airlines compared here it flies free. On 1 it fits the cabin but needs a fare that includes the full-size bag. On 25 it is too big for the cabin.
Only if the bag genuinely cannot be turned. These comparisons sort both the bag and the airline limit longest-side-first, which is how an airport sizer works — a case that is 55 deep and 20 wide is measured the same as one 20 deep and 55 wide.
Usually yes. Most airlines state their limit includes wheels and handles, which is why a case advertised as fitting a limit exactly often does not. Buy under the limit, not at it.
