Flew in and out of Incheon from two different airlines and experienced 20-30 minute delays due to air traffic at Incheon. Something to consider if transferring to another flight
There are some good things that people mentioned but for me i didn't like this airport. Restaurants and food courts close at 9. Airportrestaurants mist be open 24/7 this is a bit silly.
The LImo, deluxe taxi, maybe more expensive than the regular car. However, it is more comfortable . Besides, a driver can speak english. Even though, it is not so well :D
All the directionals advertise relaxation with massages, but they were all closed. Almost no real bars to be found. Only a few places where it took 10 minutes just to pour one beer.
Free wifi. Easy to get in and out of this airport via subways or buses or KTX trains. Taxis to seoul or anywhere else is not really worth it and expensive.
for incheon airport everything was good but immgation so bad a lot of people waiting around 2 hr for check, world best airport will good operation than u, will u see HKIA as case na
