Flights from Beijing to Seoul
The 927-kilometer hop between Beijing Capital (PEK) and Seoul Gimpo (GMP) is one of Northeast Asia's busiest bilateral corridors, clocking in at roughly an hour and thirty-five minutes block time — short enough to feel almost domestic. Air China and China Southern cover the Chinese side, typically deploying narrow-body Airbus A320-family jets, while Korean Air and Asiana Airlines mirror that capacity from the Korean end, occasionally rotating in a 737 on lighter rotations. A practical note worth flagging: Gimpo sits on the western edge of Seoul rather than at Incheon, so travelers connecting onward domestically or heading into central Seoul by metro will find it genuinely convenient, though international transit connections should be planned through ICN instead. On the fare side, shoulder periods in spring and late autumn tend to offer the most competitive economy pricing, while business-class redemptions on both Korean carriers are often more accessible on midweek departures.
