FAQ
Can I buy extra baggage online after booking?
Yes. Extra checked baggage can be pre-purchased online at twayair.com until 25 hours before departure, via My Booking (나의 예약) or the '수하물 추가 구매' (additional baggage purchase) flow.
Where do I buy extra baggage?
Buy it online at twayair.com (My Booking > additional services), or pay at the airport counter. Codeshare and interline flights cannot pre-purchase online - excess baggage is handled at the airport under the operating carrier's rules.
When is the deadline to buy extra baggage online?
Online pre-purchase, weight changes and cancellations are available until 25 hours before departure. After that no refund is given, including if the flight itself is changed or cancelled. At the airport, extra bags can be bought until check-in closes.
How many extra bags can I buy, and what are the bag limits?
Free checked allowance by fare (Event/Smart/Normal/Business): domestic 0/15/20/30 kg; Singapore & Jakarta 15/23/23/40 kg; Europe 15/23/23/40 kg; Australia 23/30/30/40 kg (from 2026-10-25: 15/23/23/40 kg); Guam/Saipan/Canada 1 x 23 kg (Business 2 x 23 kg); Mongolia/Uzbekistan 2 x 23 kg until 2026-10-24 (from 2026-10-25: 1 x 23 kg, Business 2 x 23 kg). A single checked bag cannot exceed 32 kg and the free size limit is 203 cm total (158 cm on Guam/Saipan).
How does T'way Air calculate extra baggage charges?
On weight-based routes you pay per 5 kg block online or per kg at the airport, with route-dependent rates (e.g. Incheon to Osaka: KRW 40,000 per 5 kg online / KRW 15,000 per kg at the airport). On piece-based routes (Guam, Vancouver, Ulaanbaatar, Tashkent) you pay per extra piece.
Is it cheaper to buy extra baggage online in advance vs at the airport?
Yes - online pre-purchase is cheaper. Example Incheon to Osaka: 5 kg costs KRW 40,000 online but KRW 75,000 at the airport. Airport rates are charged per kg in local currency and vary with the exchange rate.
What are the overweight or oversized baggage rules?
Excess weight above the free allowance is charged at the per-kg airport rate or per-5 kg online rate for the route. A single checked bag cannot exceed 32 kg - heavier bags must be repacked. Free checked size is 203 cm total dimensions (158 cm on Guam/Saipan).
Are there any important exceptions or restrictions?
Codeshare flights include only 15 kg and cannot pre-purchase baggage (operating carrier rules apply); interline segments also cannot pre-purchase. Weight pooling between travelling companions is allowed except on Guam/Saipan, Vancouver, Ulaanbaatar and Tashkent routes. Pre-purchased baggage is non-transferable and can only be bought once per person.
How can I pay for extra baggage?
Online payment follows the site's country currency setting; for departures from Russia, Kyrgyzstan, Laos, Vietnam, Philippines, Cambodia and Mongolia the charge is billed in USD. At the airport, payment is in local currency (USD is also accepted in the Philippines and Laos).
Can I get a refund for prepaid extra baggage if I cancel or change my booking?
Pre-purchased baggage can be cancelled and refunded free of charge until 25 hours before departure; after that it is non-refundable, including when the flight itself is changed or cancelled. Weight changes are done by cancelling and repurchasing.
