Air Seoul Baggage Fees (2026)
Quick summary
Air Seoul is an Asiana-affiliated Korean low-cost carrier flying mostly regional Asian routes. Standard fares include one free 15kg checked bag plus a 10kg carry-on, with escalating fees for anything heavier.
The bottom line on Air Seoul baggage
Air Seoul is a low-cost carrier that is more generous than most of its budget peers, since standard fares already include a free 15kg checked bag on top of a 10kg carry-on. The cost creeps in above that line: overweight tiers escalate fast, with a 16–23kg bag adding about USD 30 and 24–30kg about USD 50, so a bag that drifts just over 15kg is where casual packers get stung.
The surest way to stay ahead is to keep your free bag at or under 15kg and, if you need more, pre-pay excess online before the cut-off (4 hours international, 48 hours domestic) rather than at the airport counter. Two small habits also protect your wallet: cancel within 24 hours of booking if plans wobble, and always cancel before departure to dodge the roughly KRW 8,000 per-direction no-show penalty.

Hidden pitfalls most travelers miss
- Overweight tiers escalate fast: a 16–23kg bag adds about USD 30 and a 24–30kg bag about USD 50, so a bag that drifts just over the free 15kg gets stung.
- Prepaid excess baggage has a cut-off — 4 hours before international departure, 48 hours for domestic — after which you pay the higher airport counter rate.
- Skipping cancellation triggers a no-show penalty of about KRW 8,000 per direction, so always cancel before departure even if you can't fly.
