Will a standard carry-on fit Jeju Air?
The most common US carry-on size is 22 × 14 × 9 in (56 × 36 × 23 cm, wheels included). On Jeju Air it does not fit — 0.9 cm (0.4 in) too long, 2.9 cm (1.1 in) too deep. The common European cabin size, 55 × 40 × 20 cm, is right at the limit.
Jeju Air's cabin bag allowance holds about 44 litres. Only 5 of the 151 airlines we track have a smaller one, so bags sold as "carry-on size" in the US often won't pass here.
