MAKE THE JOURNEY COUNT
Times below are published examples, not calculated route averages. Connecting journey times include the stop. Services and schedules can change; confirm your exact dates with the airline.
| Route | Airline example | Journey time | Price information |
|---|---|---|---|

The verified examples here involve a connection. This is not a claim that nonstop service is unavailable: check current schedules for your exact dates.
COMPARE THE WHOLE COST
Compare the total journey when a connecting fare looks attractive. An extended stop can use a large part of a short Seoul break; review whether both flights and baggage are on one ticket.
We do not yet have a comparable fare sample for a reliable average. Request a quote for your dates, cabin and baggage needs; a single advertised low fare would not tell you the average cost.
THE RIGHT ARRIVAL
Heathrow, Gatwick, Stansted, Luton, City and Southend are separate airports. An early departure can require a hotel or taxi; check the first train before treating a low fare as a saving.

Airport transport information ↗For this long journey, compare the seat and cabin on every segment, not just the longest flight. Ask the airline to confirm the operating aircraft and whether the quote mixes cabins; Premium Economy and First are not available on every service.
