  • Passengers with e-tickets that need to be changed

Q I’ve logged in but my reservation is not showing up on the list of reservations. Details


After logging in, the reservation list will be displayed only when the ticket information and membership number have been linked at the time of ticket purchase.
You must inquire whether your Asiana Club membership number is linked at the place of purchase.
However, even if it is not displayed on the reservation list, you can use online check-in without logging in if you enter your reservation number (or ticket number).
Also, you may need to enter your membership number, which is required for earning miles during online check-in.

Q After entering my passport number, why does it say that I cannot check in? Details


Passengers who require additional confirmation from the Ministry of Justice due to the pre-immigration system may be restricted from being issued a boarding pass.
Check that you have correctly entered your passport information under the check-in menu, as passport information is often entered incorrectly.

Q When checking in online, why does a “check-in failed” message related to U.S. visas (ESTA) appear? Details


Due to the enforcement of the Advance Passenger Information System (APIS), all passport information entered during check-in will be sent to the United States Customs and Border Protection (CBP) on real time.

In this process, boarding passes will not be issued for passports that have not been approved through ESTA. Thus, boarding passes and tickets for exchange may not be issued online.

Passengers traveling to the U.S. for visiting purposes without a visa (ESTA users) should visit the official ESTA homepage and double-check the approval. Passengers traveling to the U.S. for purposes other than visiting should receive boarding passes at the airport counter to confirm the validity of the visa and travel documents.

However, seats assigned online will be reserved.

Q After selecting my seat, I’ve moved on to the next step but my selection has not been applied. It says that I cannot check in. Details


During the seat assignment process, the selected seat can be occupied first by other customers through different check-in procedures. Emergency exit or preferred seats (charged) cannot be selected during online check-in.

Q One of the passengers in my group cannot complete their check-in. Details


Online check-in may be limited in the following cases.

  • - Passengers for whom the service is restricted
  • - If confirmation is required from the corresponding country’s electronic system

Passengers who completed check-in using the Asiana Airlines application (APP) can find their saved boarding pass under the [Mobile Boarding Pass] menu.

After checking in online, if you received your boarding pass via Kakao notification or SMS, you can confirm your boarding pass via the link sent to you.

iPhone users can easily view their boarding pass on the Apple Wallet menu.

Q Can I cancel my online check-in online as well? Details


Yes, you can cancel your check-in during online check-in service hours. After reconnecting to the check-in menu, you can cancel under the [Cancel check-in] menu.

Q If I cancel my online check-in (seat assignment), does it also cancel my reservation? Details


Canceling your check-in does not cancel your reservation. Cancellation, changing of reservation, and ticket refunds must be processed separately from the place of purchase.

Q Can I change my seat even after I have completed my online check-in (seat assignment)? Details


Yes, you can. If you wish to change your seat, go back to the check-in menu and select [Change check-in] to proceed. At the [Change check-in] menu, not only can you can change your seat, but you can also enter your mileage number and edit passenger information.

Q I’ve entered my passport information incorrectly. Will this be a problem? Details


If you’ve incorrectly entered your passport information, your immigration process may be delayed or unexpected problems may occur.

Revisit the check-in menu and edit your information, or correct it at the airport counter.

Q Why must I enter my passport information? Details


Most countries require airlines to submit the passport information of passengers before the flight departs, for reasons of flight safety, security, and customs in the country/region.

Enter your passport information correctly, as passport information is sent to the departure/arrival city immigration office. If you are traveling to the U.S., entering additional information is required, including the address of where you will be staying.

Q I have made reservations with a traveling companion, but only I am deactivated on the passenger selection list and cannot be selected. Details


That means valid e-ticket information has not been applied, or special request items that require airport confirmation and preparations have been applied.

Q I’ve printed my boarding pass online. Must I go through a separate procedure at the airport? Details
