Overview
Seoul is one of Asia's most exciting city breaks: a fast-moving capital where Joseon-era palaces sit in the shadow of glass towers and night markets buzz well past midnight. For UK travellers it works as a standalone trip or a first stop before Busan, Jeju or onward to Japan. Flights from the UK land at Incheon International Airport (ICN), the country's main gateway, roughly an hour from the centre by train. Check the price charts on this page to see how current fares are moving before you book.
Best time to fly to Seoul
Seoul has four distinct seasons. Autumn, from late September to November, is the local favourite: dry, clear days, comfortable temperatures and vivid foliage. Spring (April to May) brings mild weather and cherry blossom, though it is popular and fares reflect that. Summer is hot and humid with a wet monsoon spell in July, while winter is cold and crisp, often below freezing, but quieter and usually kinder on the wallet. Avoid the Korean holidays of Lunar New Year (Seollal) and Chuseok, when demand spikes. The When to book chart above shows how prices shift across the year.
Airlines and routes
Korean Air and British Airways fly nonstop from London Heathrow to Incheon, with a typical flying time of around 11 to 12 hours outbound; return legs and routings that avoid Russian airspace can run a little longer. There are no direct flights from Manchester or other UK regional airports, so travellers outside London connect through a European or Gulf hub — KLM via Amsterdam, Lufthansa via Frankfurt or Munich, Air France via Paris, or Emirates, Qatar Airways and Etihad via the Gulf. Allow roughly 14 to 17 hours door to door from Manchester, Birmingham or Edinburgh. One-stop fares are often cheaper than nonstop, so it pays to compare both.
Things to do in Seoul
Seoul mixes centuries-old heritage with cutting-edge design and some of Asia's best street food. A few highlights to build an itinerary around:
- Gyeongbokgung Palace: the grandest of the royal palaces, with a colourful changing of the guard ceremony.
- Bukchon Hanok Village: steep lanes of restored traditional houses set between the main palace district.
- N Seoul Tower: sweeping views over the city from the top of Namsan mountain, reached by cable car.
- Myeongdong: Seoul's busiest shopping street, at its best after dark for skincare shops and food stalls.
- DMZ day trip: a guided visit north to the border with North Korea, one of the region's most thought-provoking excursions.
At Incheon International Airport (ICN)
Incheon sits about 48km west of central Seoul on Yeongjong Island. The quickest route into town is the AREX Airport Railroad express, which reaches Seoul Station in roughly 45 minutes; the all-stops line costs less and serves more districts. Airport limousine buses run directly to many hotels and neighbourhoods, which is handy with luggage, while a taxi takes around an hour and costs considerably more. Pick up a rechargeable T-money card at the airport to use on trains, buses and the metro.
Top tips for finding cheap flights to Seoul
- Book roughly two to five months ahead for economy — last-minute long-haul fares to Seoul are rarely a bargain.
- Fly midweek and outside school holidays; Tuesday and Wednesday departures are typically cheaper than weekends.
- Use a flexible-date search to compare a nonstop with a one-stop itinerary, as the connecting option often wins on price.
- Travel in the shoulder months of late autumn or winter, and check the price charts on this page before you commit.
Travel essentials
UK passport holders can currently visit South Korea visa-free for tourism for up to 90 days. Korea also operates the K-ETA electronic travel authorisation scheme, and entry rules can change, so check the latest advice on GOV.UK and the official K-ETA website before booking. The currency is the South Korean won (KRW); cards are accepted almost everywhere, but carry a little cash for markets and small eateries. No vaccinations are required for entry, though comprehensive travel insurance is strongly recommended.
