Common questions before you pack

11 source-matched airline rules publish exactly 40 x 30 x 20 cm as a cabin limit, and the same bag fits inside 97 more published rules. The tables list fare, weight, source and match date.

40 x 30 x 20 cm is 15.7 x 11.8 x 7.9 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.
