Got a few hours to spare at Incheon International Airport? Check out the CGV Movie Theater in Terminal 1. There’s no better way to kill a few hours than by seeing what is on the silver screen -- after all, a trip to the theater could even be considered a cultural experience, as you could see the latest Korean flick while you are there.
Fashion and cosmetics are two of South Korea’s biggest businesses nowadays, and Incheon International Airport certainly does these two industries proud. The selection of premier brands and products is truly expansive in the duty free shopping areas of the airport. Travelers can find a wide selection of both international and homegrown Korean products available for purchase.
Many hotels offer complimentary shuttle service to and from Incheon International Airport. For travelers looking to go straight to their hotel after their flight to Seoul, options to consider are Grand Hyatt Incheon, Hotel Hu Incheon Airport and Orakai Songdo Park Hotel. There is even a capsule hotel, Capsule Hotel Darakhyu, located right within the airport.
If you need to store some luggage at ICN, lockers are available on the third floor near Check-in B and Check-in N. Storage is available 24h and costs roughly $5 to $9 per day.
If you need to smoke, there are a variety of dedicated smoking rooms on the first and third floors of both Terminal 1 and Terminal 2. Passenger terminal: 2 locations in public area 1F; 6 locations in departure area 3F; 1 location at the domestic airline office 2F. Concourse: 2 locations in 2f; 4 locations in 3F.
If you want some muscle relaxation after a long flight to ICN, consider checking out the spas for skin care and massage treatments. In Terminal 1, they’re near Gates 25 and 29; in Terminal 2, they’re near gates 231 and 268. Both are open from 7 am to 8 pm.
Do you have a long layover schedule in ICN and need a place to relax and rest? They have a spa in T2 East where you can relax during layovers.
