Cheap flights from London to Jeju

September is the cheapest month listed for this route, and the price calendar runs from September through March, so your realistic window is autumn into late winter. Outside those months no dated fares are shown here, which makes the quieter weeks either side of the festive period worth a look. On a connecting route like this one, the day you leave and the length of the stop move the price more than the season does, so try a couple of departure days before you settle. Compare the calendar first, then decide.

Every carrier listed for this route is full-service, and none of them fly London to Jeju nonstop. Asiana Airlines and the Chinese carriers — Air China, Shenzhen Airlines, China Southern Airlines and China Eastern Airlines — bring you in through Asia, while Finnair, Air France, Austrian and Air Europa route you through Europe and Qatar Airways goes by way of the Gulf. What is included differs by airline and by fare: baggage, seat selection and the freedom to change a ticket are not the same across all of them, so read the fare rules for the exact flights you pick.

Jeju Intl. is the only airport on the island, so every flight into Jeju lands there. It sits close to Jeju City, which means a short transfer into the main urban area rather than a long ride from a distant terminal. Buses and taxis are the usual ways into town, and a rental car makes sense if you plan to see the rest of the island. Because you arrive off a connecting flight, leave some slack in your plans for a delayed first leg, and check whether your bags are tagged through to Jeju or need collecting at the transfer point.

Country facts: Wikidata

• Decide which London airport you are leaving from — London City, Gatwick, Heathrow, Luton or Stansted — before you compare fares, because the price depends on it.
• Check where you change planes and how long the layover is, since there is no nonstop service on this route.
• If the legs are booked on separate tickets, allow room for delays and confirm whether your bags are checked through.
• Look at the baggage allowance and fare conditions with the airline you choose, as they vary between carriers.
• Confirm the entry rules and any visa or travel authorisation for South Korea before you pay.
• Use the price calendar from September to March, and remember September is the cheapest month listed.
