About flying to South Korea
Flights to South Korea are well covered by the major comparison feeds. The main international gateways (ICN, GMP, PUS, CJU) all have direct connections from one or more UK airports, and onward connections via European hubs (Frankfurt, Amsterdam, Paris, Madrid, Istanbul) often surface cheaper than non-stop options if you're flexible on timing. Once inside South Korea, Seoul, Busan, Jeju are the most-searched destinations on Exmoway — the route guides linked above include airline lists, typical durations, and best-months strips for each.
Pricing on routes to South Korea follows the seasonal pattern shown in the colour-coded "best months to fly" strip above. Green months are the cheaper end of the year — usually outside school holidays, public holidays, and the destination's peak weather window. Red months (peak) can be 50–100% more expensive for the same itinerary, so even a one-week shift either side of a peak window can produce real savings if your dates are flexible. Booking 8–16 weeks ahead for long-haul, or 3–8 weeks for short-haul, generally catches the cheap fare buckets before they sell out.
The currency in South Korea is KRW ₩, and the official language is Korean. UK travellers should check the visa rules in the "travel essentials" panel below before booking — most visa-free arrangements have a maximum stay limit and may require a passport with six months' validity beyond your travel dates. Local SIMs, ATM availability, and tipping conventions vary by region; we recommend the relevant national tourism board's official guidance for the latest details.
