Seoul is served primarily by two airports: Incheon International (ICN), the city’s main international gateway and a full-service hub for major carriers such as Korean Air and Asiana, and Gimpo (GMP), which functions more as a domestic and short-haul regional airport with many low-cost and legacy domestic flights. Incheon lies about 48–60 km west of downtown Seoul and can take roughly 45–70 minutes by airport express train or 60–90 minutes by car depending on traffic; fares for the AREX express/train run from modest to moderate levels and buses and taxis add flexibility. Gimpo is much closer, around 15–20 km from the city center, typically reachable in 30–45 minutes by subway or 30–60 minutes by car, often at lower transport cost. Pros: Incheon offers extensive amenities and international connections; Gimpo is quicker for domestic trips. Cons: Incheon’s distance can add transit time and cost, while Gimpo has fewer long-haul options and smaller lounges.

Noi Bai International Airport (HAN) is Hanoi’s main international gateway and a regional hub handling most long-haul and major domestic flights, while smaller, more budget-oriented operators sometimes use nearby secondary facilities for specific charters. The airport sits about 45 km (roughly 1–1.5 hours in normal traffic) from the city center; transfer options include airport buses (45–90 minutes, low fares), taxis and ride-hail services (about 45–70 minutes, mid-range fares), and private transfers. Typical carriers range from full-service Asian and Middle Eastern airlines to low-cost Vietnamese carriers. Pros: extensive international connections and modern terminals; cons: distance from central Hanoi and traffic-dependent journey times.

The cost of a one-way flight from Seoul to Hanoi ranges from $111 (October 2026) to $203 (May 2027). On average, the ticket price is about $142–$145.
