Carry-on size limits by airline alliance

An alliance shares lounges and connections, not one carry-on rule: each member publishes its own limit. For the 48 verified alliance airlines with an included, measured cabin bag, the table gives each alliance's average total size, its strictest and most generous member, and every member ranked.

Data from 220 verified airlines, last checked on 11 October 2026.

Which alliance has the strictest carry-on rules?

SkyTeam members have the smallest cabin bag on average, 116.3 cm (45.8 in) in total across 15 airlines. Star Alliance members are the most generous on average, at 117.2 cm (46.1 in) (21 airlines). The 141 verified airlines in no alliance average 113.7 cm (44.7 in).

The three alliance averages are only 0.9 cm (0.4 in) apart, while members of the same alliance differ by up to 14 cm (5.5 in): on a trip with connections inside one alliance, the strictest member on your route sets the size you can carry, not the alliance.
