Air Seoul

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

The context in a few words

Air Seoul flies from Corée du Sud on a full-service model inherited from traditional aviation. In practice, that translates to a more permissive baggage policy than budget airlines — though it's still worth checking the exact figures before check-in.

55x40x20 cm and 10 kg: the policy is on the lenient side. Travellers used to low-cost gauges will breathe easier here.

On the ground, posted rules and counter practice don't always align. Air Seoul publishes 55x40x20 cm and 10 kg as the upper bound, and gate agents typically allow 1–2 cm of leeway before routing to hold. Don't bank on it — tolerance evaporates the moment the flight fills up.

In daily use, dimensional checks are less frequent than on low-cost airlines, but the rules apply once a flight fills up. On busy short-haul routes, an oversized cabin bag may end up in the hold for free — a service that quickly becomes mandatory.

On Air Seoul, unclear personal-item language calls for caution. A thin laptop sleeve clears in 95% of cases; a backpack sized like a second cabin bag, much less. When in doubt, the safe play is to consolidate everything into the main bag.
