Beijing is served primarily by two airports with distinct roles. Beijing Capital (PEK) has been the city’s main international hub for full-service carriers such as Air China and many global airlines, while Beijing Daxing (PKX) is a newer, high-capacity airport handling a mix of international and domestic routes and attracting both legacy and low-cost carriers. Capital sits about 25–30 km northeast of the city center and Daxing roughly 45–50 km to the south; travel times can range from 30–60 minutes by express train or 45–90 minutes by car depending on traffic. Public transport options include intercity express trains, metro links and airport shuttle buses; fares typically range from modest metro fares to higher express-train and taxi costs. PEK may be more convenient for Tiananmen-area arrivals, while PKX offers modern facilities and possibly lower fares on some routes; expect busier terminals and varying comfort depending on carrier and time of day.

Seoul is served by two main airports with distinct roles. Incheon International (ICN) is the primary international hub, typically handling long-haul and many full-service carriers; it’s located about 48 km west of downtown Seoul and can take 45–70 minutes by express train or 60–90 minutes by car depending on traffic. Airport Railroad Express (AREX) and intercity buses are common options, with fares usually ranging from moderate to higher for the express services. Gimpo Airport (GMP) functions more as a domestic and short-haul gateway, frequently used by budget and regional carriers and situated roughly 15 km west of central Seoul; travel time is often 20–40 minutes by subway or 25–50 minutes by taxi. Gimpo can be more convenient for quick city access and shorter connections, while Incheon usually offers broader international connectivity, more amenities, and duty-free options—at the cost of longer transfers and sometimes higher transport fares.

In different months, ticket prices from Beijing to Seoul vary: minimum — $99 (December 2026), maximum — $215 (August 2027). Typically, the flight costs $123–$128.
