Seoul is served primarily by two airports with different roles. Incheon International (ICN) is the city’s large international hub, handling most long-haul and premium carriers and often used for transfer traffic; it sits about 48 km west of downtown and is typically reached in 45–70 minutes by airport railroad (AREX) or express bus, with fares usually ranging from budget-friendly local train prices to higher express services. Gimpo (GMP) functions as a shorter-haul and low-cost gateway, serving domestic flights and regional routes to Japan and China; it lies roughly 15 km from central Seoul and can be reached in 20–40 minutes by subway or taxi. ICN tends to offer more extensive lounges, shopping and customs facilities but can involve longer transfers to the city, while Gimpo is generally quicker for inner-country travel though smaller and with fewer long-haul amenities.

Beijing is served mainly by Beijing Capital International (PEK), a large international hub handling most full-service and many long-haul carriers, and Beijing Daxing International (PKX), a newer mega-hub that has attracted both legacy and growing low-cost operators. Capital lies about 25 km northeast of Tiananmen (roughly 45–60 minutes by taxi in moderate traffic) while Daxing is approximately 46 km south of the city center (about 45–75 minutes by road). Both airports connect to central Beijing by express train/airport express lines and buses; fares for rail are typically modest, and airport taxis or rideshares can be mid-range depending on distance and time of day. PEK can be busy but convenient for transfers; PKX is modern with streamlined facilities but may require extra travel time to some districts. For budget-conscious travelers, both airports can host lower-fare options, though full-service carriers usually operate from Capital.

The minimum one-way ticket price from Seoul to Beijing is $138 (July 2026), while the maximum is $166 (April 2027). On average, a ticket costs $151–$153.
