Common questions before you pack

26 source-matched airline rules publish exactly 55 x 40 x 23 cm as a cabin limit, and the same bag fits inside 19 more published rules. The tables list fare, weight, source and match date.

55 x 40 x 23 cm is 21.7 x 15.7 x 9.1 in. Airlines round conversions differently, so always compare in the unit the airline itself publishes.

Sometimes — limits are checked edge by edge, and rotating the bag can help. Enter your exact measurements in the checker; any edge within 1 cm of a limit should be treated as a gamble at the sizer.
