Korean Air and Asiana Airlines travelers in Korea can now use their mobile phones to check in for international flights. The airlines will launch mobile check-in services in cooperation with SK Telecom. The services are limited to SK Telecom users flying with either of the two carriers. Using a mobile Internet connection on their phone, travelers can choose their seats and check in by inputting their reservation number and residence registration number. Upon arriving at Incheon International Airport, they can issue their boarding pass using self-check-in machines by inputting a barcode downloaded to their phone and their passport number. Luggage must be checked at a separate counter.

Asiana will launch the service on Tuesday. Korean Air has not yet decided on a definite launch date but is looking to begin the service soon.
