Flights from Seoul to Beijing
The 927-kilometre hop between Seoul's Gimpo Airport and Beijing Capital is one of Northeast Asia's most travelled short-haul corridors, covered in a typical block time of around one hour and thirty-five minutes. Four carriers share the route — Air China, China Southern, Korean Air, and Asiana Airlines — and all four typically deploy narrowbody jets such as the Airbus A321 or Boeing 737, though Korean Air occasionally rotates wider equipment during peak periods. One practical point worth noting: travellers connecting onward from Beijing Capital should budget generously for transit, as the airport is large and immigration queues for those requiring a visa can run long; China's 144-hour transit visa exemption, however, makes a tight Beijing stopover considerably more feasible for many nationalities than it once was. Fare-wise, midweek departures tend to yield softer pricing, and autumn shoulder months — late October into November — often produce the most competitive economy fares before Golden Week demand resets the market.
