Common questions before you pack
22 source-matched airline rules publish exactly 40 x 30 x 15 cm as a cabin limit, and the same bag fits inside 110 more published rules. The tables list fare, weight, source and match date.
40 x 30 x 15 cm is 15.7 x 11.8 x 5.9 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.
