International Carry-On Size. Outside of the U.S. the standard carry-on baggage size is smaller (this relates to flights originating outside the U.S. and with a destination outside the U.S.) Here, the rule of thumb is about 21, and not the 22 and above carry-on size. As with any rule, exceptions abound and it is a good idea to visit the site of all of the carriers you plan to use while abroad to get a consensus.
