Flights to Seoul— Search, Compare & Pay in Instalments

Korean Air and Asiana Airlines operate the most direct routes to Seoul's Incheon International Airport (ICN) from cities across Asia, Europe, and North America. Singapore Airlines, Cathay Pacific, and British Airways also fly direct on select routes. You can compare all available direct and connecting options on Laters.com.

January and February are typically the cheapest months to book flights to Seoul, when demand is low and winter temperatures keep leisure travellers away. Average one-way fares from Southeast Asian cities can drop to around USD 180 during this window. Avoid booking for late March or early April without significant lead time, as Cherry Blossom season drives fares up sharply.

Yes. Laters.com supports several BNPL providers at checkout for Seoul flights, including Atome, Klarna, Kakaopay, and Afterpay depending on your location. You select your preferred provider at checkout, receive instant approval, and your e-ticket is issued immediately. The fare is then split into three or four payments over the following weeks.

Most BNPL providers used on Laters.com perform a soft credit check, which does not affect your credit score. Klarna and Afterpay both use soft checks for their standard instalment plans. If you are concerned, check the specific provider's terms before completing checkout.

Most Western European, Australian, and many Southeast Asian passport holders can enter South Korea visa-free for stays up to 90 days, or via the K-ETA (Korea Electronic Travel Authorisation) which can be completed online in a few minutes. Visa requirements can change, so always verify current rules at the official Korean Immigration Service website (immigration.go.kr) before travelling.

The AREX Express Train is the fastest and most reliable option, taking approximately 43 minutes to Seoul Station for KRW 9,500. Airport limousine buses cover a wider range of destinations for KRW 10,000 to 17,000 and take 60 to 90 minutes depending on traffic. Metered taxis and Kakao Taxi are also available outside arrivals and typically cost KRW 65,000 to 90,000.

Spring (late March to May) and autumn (September to November) are widely considered the best seasons, offering mild temperatures and the city's most photogenic scenery: Cherry Blossoms in April and golden foliage in October. Summer is hot and humid with a rainy season in July, while winter is cold but uncrowded and inexpensive. Note that spring and autumn are also the most popular and expensive periods to book flights.

Direct flights from London Heathrow to Seoul Incheon take approximately 11 to 12 hours with Korean Air or British Airways. Connecting flights via hubs such as Dubai, Doha, or Hong Kong typically add two to five hours to the total journey time. Laters.com lets you compare both direct and connecting options side by side.

Your e-ticket is issued immediately after your booking is confirmed, regardless of which BNPL provider you use. You do not need to wait for your first instalment to clear before receiving your travel documents. A confirmation email with your itinerary and e-ticket is sent to the address you provide at checkout.

Incheon has two passenger terminals. Terminal 2 is used exclusively by Korean Air, Delta, Air France, and KLM. All other international carriers use Terminal 1. The two terminals are connected by a free shuttle bus that runs every five to ten minutes, but it is worth confirming your terminal before you travel to avoid a last-minute dash.
