Hanoi is served primarily by Noi Bai International Airport (HAN), the city’s main international gateway and regional hub that handles a mix of full-service carriers and low-cost airlines. Located about 45–50 km north of central Hanoi, travel time can be roughly 30–60 minutes by car depending on traffic; airport buses and shuttle services typically take 40–70 minutes with fares usually in the budget-friendly range, while metered taxis or ride-hailing can be quicker but cost more. Noi Bai is generally seen as good for international connections and budget options, though peak-hour congestion and transfer distances inside the complex can make some transfers less convenient.
Seoul is served mainly by two airports with distinct roles. Incheon International (ICN) is the city’s primary international hub, handling long-haul and premium carriers alongside full-service Asian airlines; it’s often perceived as pricier but offers extensive facilities. ICN lies about 48 km west of downtown Seoul, reachable by AREX express (approx. 43–55 minutes), regular AREX trains (55–70 minutes), airport limousine buses (60–90 minutes), or taxi (60–90 minutes depending on traffic); fares typically range from mid to high for trains and buses, with taxis costing considerably more. Pros: modern terminals, frequent connections, wide amenities; cons: longer transfer time to central Seoul. Gimpo International (GMP) functions as a secondary airport focused on domestic and short-haul regional flights, commonly served by low-cost and full-service Korean carriers; it’s much closer to the city (about 15–20 km west), with subway and AREX links taking roughly 20–30 minutes and shuttle buses or taxis offering similar travel times at modest fares. Pros: convenience and shorter transfers; cons: fewer long-haul international options and more limited facilities compared with Incheon.
