Asiana carry-on: cabin pieces and personal items have separate limits
Both cabins also allow one personal item within 40 × 30 × 20 cm for storage under the seat ahead. Unlike an allowance expressed as a combined weight, Asiana’s Business table states the weight for each main carry-on bag. Check large or heavy baggage at the airport counter rather than planning to resolve it at boarding. Asiana’s guidance says baggage, including duty-free items, cannot be checked in at the gate as a planned service, although an otherwise compliant bag may still be carried in the hold when cabin space requires it. Count shopping and additional bags before reaching the gate, and check another operator’s cabin allowance separately.

Asiana checked baggage: U.S., other international and domestic rules differ
Asiana’s published international allowance normally gives Economy passengers two 23 kg pieces on U.S. routes and one 23 kg piece on other international routes. Business normally includes two 32 kg pieces. Each standard piece is limited to 158 cm total dimensions. Asiana specifies that U.S. territories such as Saipan use its non-U.S. allowance rules, so the destination’s political classification is not enough to choose a baggage row. Korean domestic travel uses a weight allowance instead: 20 kg in Economy and 30 kg in Business under the published standard rules. A domestic segment connected with an international flight can follow the international allowance, while an Air Busan-operated domestic codeshare uses Air Busan’s rules. Check the ticket and the operating carrier before applying a long-haul piece allowance to a separate domestic booking.

Asiana prepaid extra baggage: buy additional pieces, not extra weight
Asiana’s prepaid excess-baggage service is available for eligible international flights until 24 hours before departure. It purchases additional standard pieces rather than covering excess weight. Domestic flights are not eligible, and capacity or payload restrictions can prevent purchase. Check the route-specific quote and the service conditions before treating the advertised advance discount as available for your ticket. The service has important restrictions for transfer itineraries and other-airline codeshares. Currency changes after reissue can also affect eligibility, and baggage cannot be purchased through this service while you remain checked in. If the itinerary changes, tickets bought through an agency do not receive the same automatic ancillary refund handling as direct Asiana purchases. Ask the original seller to check the unused baggage service rather than paying again without resolving the first purchase.
