Seoul is served primarily by two airports with distinct roles. Incheon International (ICN) functions as the international gateway and full-service hub, handling most long-haul and many regional carriers; it’s often perceived as mid-to-high priced for transfers and services. Located about 48 km west of downtown, it’s reachable by AREX express (about 45–55 minutes, higher fare) or all-stop train (about 55–70 minutes, cheaper), plus airport limousines and taxis (60–90 minutes depending on traffic). Pros: modern facilities, extensive international connections and amenities; cons: longer transfer time to central Seoul compared with the closer airport. Gimpo (GMP) operates more as a domestic and short-haul regional airport, serving budget and full-service carriers on domestic routes and some nearby international flights. Situated roughly 16 km west of the city center, Gimpo is typically quicker and cheaper to reach—AREX or subway lines take about 20–30 minutes and fares are modest, while taxis can be 30–45 minutes. Pros: convenience for domestic travel and shorter transfer times; cons: fewer long-haul options and more limited lounges and services compared with Incheon.
Lisbon Humberto Delgado Airport (LIS) is Portugal’s main international gateway and typically serves a mix of full-service carriers and low-cost airlines, so you can expect both premium and budget options. Located about 7 km (4–5 miles) northeast of the city centre, travel times are usually short: the metro takes roughly 20–30 minutes (single fares around €1.50–€3), taxis are generally 15–25 minutes with fares that can vary by time and traffic, and airport shuttles or rideshares are common. The airport is convenient for most central hotels and business districts, with modern terminals and decent transfer connections, though peak-hours can bring crowded security lines and higher taxi surcharges. Overall it’s a well-connected hub that balances comfort and cost for most travellers.
