Brussels Airport (BRU) serves as Belgium’s main international hub, handling long-haul and intra-European flights for full-service carriers such as Brussels Airlines alongside many legacy and low-cost operators. Located about 12 km (roughly 20–30 minutes by car) northeast of the city center, it’s well connected by train (around 17–20 minutes to Brussels-Central) and by several bus and shuttle options; fares can vary from modest regional train prices to higher express transfers. The airport is typically seen as mid-to-premium in comfort, with extensive lounges and shopping, though peak times may mean longer queues. Pros: fast rail link and broad route network; cons: can be busy at peak periods and transfers to some suburbs may take longer.

Seoul is served by two main airports with distinct roles. Incheon International (ICN), west of the city on reclaimed land, is the country’s primary international gateway and a major Asian hub for full-service carriers such as Korean Air and Asiana; it typically handles long-haul and transfer traffic and can be perceived as mid-to-upper range in terms of service and fees. Transport to central Seoul usually takes about 45–70 minutes: the Airport Railroad Express (AREX) takes roughly 43 minutes to Seoul Station, while airport buses range from 50–80 minutes depending on traffic; fares for rail are commonly in the mid-range and buses are modestly priced. Pros: modern facilities, many transfer amenities and frequent international connections; cons: farther from downtown and travel times can vary with road congestion. Gimpo International (GMP), closer to western Seoul, functions mainly as a domestic and short-haul regional airport with a growing number of low-cost and domestic flights; it often serves budget-conscious travelers and carriers operating short hops to nearby cities and regional hubs. The airport is around 20–30 minutes from central Seoul by AREX, bus or taxi; travel times can be 20–40 minutes depending on traffic, with fares typically lower than long-distance airport transfers. Pros: quicker access to the city and convenient for short domestic trips; cons: fewer international connections and smaller range of services compared with the larger Incheon hub.

In different months, ticket prices from Brussels to Seoul vary: minimum — $415 (November 2025), maximum — $585 (December 2025). Typically, the flight costs $509–$573.
