Jeju Air

Allowed dimensions: 55x40x20 cm · Maximum weight: 10 kg

The context in a few words

Jeju Air belongs to the heritage carriers of Corée du Sud, the airlines that grew alongside commercial aviation and now run dense international networks. Carry-on policy reflects that pedigree: roomy allowances, broadly aligned with IATA standards.

Allowed format: 55x40x20 cm, 10 kg. That's generous compared with what most European low-costs publish — a real argument for travellers weighing options.

In concrete terms: a typical "cabin format" suitcase weighs 2–3 kg empty for 55×40×20 cm. On Jeju Air, once filled, the usable margin against the 10 kg ceiling shrinks to a few kilos. Frequent travellers tune the bag to exact spec to avoid gate-side reclassification fees.

Tip from the road: on these airlines, the cabin allowance is often paired with a personal item (handbag, laptop bag). Using both tiers properly maximizes capacity without overshooting.

The personal item — handbag, sleeve, underseat bag — makes all the difference on long flights. On Jeju Air, used well, it frees the cabin case for essentials and keeps liquids, electronics and papers within reach during the flight.
