International carry-on rules are not universal. The same suitcase that boards smoothly in New York can be weighed at the gate in London, sized at the desk in Tokyo, or sent to the hold on a budget flight in Europe.

Hybrid and aluminum suitcases often get compared because they share one major feature travellers care about: a more structured, secure closure than a standard zipper.
