What's the difference between Incheon Airport t 1 and t2?

Different airlines, different locations, different services.

1, the airlines are different. T 1 mainly includes Asiana Airlines, Seoul Airlines and other foreign airlines, including other domestic airlines except Xiamen Airlines, and airlines in the United States and Canada except Delta Air Lines. T2 is mainly Korean Air, KLM, Aeromexico, Aeroflot and some SkyTeam airlines (Delta, Xiamen Airlines, etc.). ).

2, the position is different. T2 station differs from T 1 station by 15km.

3. Different services. T2 is a new terminal, where the security doors are all 360 automatic, and there are few T2 airlines, so there are fewer people than T 1, and the customs queue is much faster than T 1. Changing boarding passes is basically self-help, just change the checked baggage in the past.
