Some air travelers in Korea can now use their mobile phones to check in for international flights. Korean Air and Asiana Airlines said Monday that they 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.

According to a recent report from Korea’s Digital Chosunilbo, mobile-enabled air travelers in Korea will be able to check-in for international flights using their SK Telecom mobile phone.

While limited initially to the one mobile operator and two airline carriers, consumers will be able to make seat selection and complete electronic check-in to avoid long lines and delays. Upon arrival at Incheon International Airport, passengers who have used the online mobile service will be able to produce boarding passes at special kiosks.

Asiana began offering the service this week, while Korean Air plans to start ’soon’, the report states. No costs were mentioned for SK Telecom users who wish to take advantage of the service. [english.chosun.com]
