Most Online Check-in failures are caused by wrong information entered (date of birth, passport number etc). Our system sends each passport information to the departing and arriving airport immigration office and receive a response for each passenger’s travel permission. Wrong or invalid information will not receive travel permission and check-in will fail. Please double check your travel information and proceed to check-in.
Check-in can fail in the following circumstances:

1. Additional travel documents (visa, travel document, return ticket etc.) needs to be validated.
- Passenger who need additional travel document checks can be assisted by an airport agent. Passengers are responsible for obtaining all necessary travel documents and for complying with the laws of each country from, through or to. Please re-confirm the travel documents required for your journey and prepare all the documents necessary. Asiana Airlines will not be liable for any damages or costs caused by the lack of travel documents.
2. Failure to receive response from immigration office.
- Unstable network may receive false responses. Try entering dummy information and re-enter your correct travel information and proceed check-in.
3. US bound Flights
- Passengers traveling to U.S. territory may be selected for secondary screening. Passengers who are subject to secondary screening cannot be checked in online or use kiosks to check-in. Please receive additional information from a check-in agent at the airport.
