Flying to Seoul — what to know

Seoul is a long-haul destination from the UK, suited to a culture and food trip. The 11h flight from London makes it a realistic two-week trip option, with regional UK airports — Manchester, Edinburgh, Birmingham — adding direct service on the busier routes. Fares sit in the premium long-haul bracket on this corridor, with one-way prices from £520 when you catch the right week.

January typically delivers the cheapest fares (around £546 return on average), with prices climbing through August when seasonal demand peaks (£1352+). On the ground, South Korean won (KRW) is the local currency and Korean the dominant language — English coverage is solid in tourist quarters and at the airport. Visa: K-ETA required — apply online; UK passport holders eligible. 8–14 weeks ahead is the long-haul sweet spot — earlier doesn't reliably help, later starts to hurt; last-minute bookings on this route can run two to three times the cheapest fare we see.
