Flights from Beijing to Seoul
The 903-kilometer hop between Beijing Capital (PEK) and Seoul Incheon (ICN) is one of Northeast Asia's busiest short-haul corridors, clocking in at around an hour and thirty minutes block time — short enough that business travelers frequently do it as a day trip. Air China and Korean Air dominate with the highest frequencies and typically deploy narrowbodies such as the Boeing 737-800 or Airbus A321, while China Southern and Asiana round out the schedule with similar equipment; Korean Air occasionally upgrades to a widebody on peak departures, making its business class a genuinely comfortable option on a route where premium seats are otherwise modest. Practically speaking, arriving into Incheon rather than Seoul's domestic Gimpo airport means budget an extra 45–60 minutes to reach central Seoul via the AREX express train. Fares tend to soften noticeably in January and February after Lunar New Year travel, and midweek departures consistently yield better availability than Friday or Sunday, which are crowded with weekend leisure travelers moving between the two capitals.
