Your guide to booking Seoul flights

From booking to airport arrival, find tips to help you plan your flight with more confidence.
  • For the best chance at a low fare to Seoul, aim to book around 21 weeks before you fly. That window historically saves about 29% versus last-minute pricing based on KAYAK booking data over the last 12 months.
  • For flights to Seoul, recent KAYAK data shows that stronger deals tend to land around $919 round-trip. If you see a fare below that threshold, it's a strong deal – book before the price climbs back up.
  • If you can choose when to go, time your trip to Seoul around January. Round-trip fares historically average $990 that month – typically the cheapest month to travel based on the last 12 months.
  • Before you book:

    • Check the route's typical price range so you can spot a deal.
    • Confirm baggage fees and seat-selection costs on budget carriers.
    • Verify whether you need any travel documents beyond ID.
    • Pick a departure airport, since your nearest may not be the cheapest origin.
  • Shift your departure to evening to save up to $94 per round-trip. Evening flights to Seoul average $1,201 compared to $1,295 for noon flights. See the time-of-day chart above for the full breakdown.
  • Bag allowances vary by airline, fare type, cabin class and route. On flights to Seoul, some airlines may include bags at no extra cost. For example, AIR PREMIA includes a cabin bag and a checked bag in Economy Class, Asiana Airlines includes a cabin bag and a checked bag in Economy Class and Korean Air includes a cabin bag and a checked bag in Economy Class. Always check the fare details before booking, since bag policies can change by ticket type.
  • Once you arrive in Seoul, a few great places to start are Dongdaemun Market, COEX Convention and Exhibition Center and Lotte World. These are popular with first-time visitors and can give you a good feel for the area.
  • For those wanting a quiet place to pray, ICN offers prayer rooms in both Terminal 1 (on the 3rd floor near Gate 24, on the 4th floor west side, and at the 4th-floor center) and Terminal 2 (on the east side of the basement first floor).
  • Travelers with flights to Seoul will almost certainly land at Incheon International Airport (ICN), Seoul’s major international airport. However, Incheon International is not the only airport in Seoul; Gimpo International Airport also serves the city. Gimpo International was originally the major airport of Seoul, but nowadays it is a secondary and more domestically-focused airport.
  • Looking for a place to relax while at Incheon International Airport? Multiple Relax Zones are located throughout the airport, allowing travelers to find lounge chairs and electronic outlets. There is also a Nap Zone with numerous plush recliners specifically designated for napping.
  • 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.
