First identify which airport step was missed. Air Busan’s international fare rules distinguish a passenger who misses the airport check-in deadline from a checked-in passenger who misses the boarding gate. Those states can lead to different no-show treatment.
Which deadline did you miss?
Check the departure airport’s check-in deadline on the booking and airport guidance. Air Busan treats failure to complete airport check-in by that deadline as a counter no-show.
If check-in was completed, examine the boarding record and gate timing instead. The current Air Busan international fare page states that the boarding gate closes 10 minutes before departure. Missing that closure is the gate no-show branch. Ten minutes is the airline’s category boundary; it is not a safe airport-arrival allowance.
Do not classify the case from the scheduled departure time alone. A boarding pass can show that check-in occurred, but it does not by itself prove arrival at the gate before closure.
Build the evidence chain before asking about money
Keep the reservation number, ticket and itinerary, the airport and flight number, scheduled departure time, any check-in or boarding-pass record, and messages or timestamps showing what happened. Write down whether staff identified the case as counter or gate no-show.
Ask Air Busan to confirm the recorded state first, then ask which no-show fee and separate refund fee apply to each affected sector. The international page lists KRW120,000 for counter no-show and KRW240,000 for gate no-show, per person on a one-way basis. Its counter exception for Busan–Qingdao and Busan–Da Nang is KRW100,000. These are no-show charges, not a complete refund calculation.
Separate refundable components from the airfare
The same rules treat the no-show fee and refund fee as separate items. They also describe a limited case in which airport tax and fuel surcharge remain refundable when the applicable fees exceed the airfare. That does not mean the airfare is fully refundable.
Ask for a written breakdown showing the fare, each fee, and any tax or surcharge returned. Keep the response with the original payment record before deciding whether another booking is needed.
If the record is unclear
Contact the airline through the current channel shown on its fare page and provide the evidence above. Ask it to identify the exact no-show category and remaining ticket status. Do not assume that a late arrival can be appealed, that the missed flight can be reinstated, or that a new seat will be issued.
If travel is still necessary, price a separate replacement only after confirming what remains usable in the original itinerary. A new purchase does not settle the old ticket’s fee or refund position.
