Seoul is served primarily by two airports with distinct roles. Incheon International (ICN) functions as the city’s international hub, handling most long-haul and full-service carriers; it’s about 48 km west of downtown and typically reached in 40–60 minutes by AREX express or airport limousine buses, with fares generally higher than local options. Gimpo (GMP) operates more as a domestic and regional gateway, catering to budget and short-haul flights and lying roughly 15–20 km from central Seoul; travel by AREX commuter train or bus usually takes 20–40 minutes at lower fares. Pros: Incheon offers extensive facilities and international connections, while Gimpo can be faster and cheaper for short trips. Cons: Incheon’s distance can add transit time and cost, and Gimpo may be crowded during peak periods.

Singapore Changi Airport (SIN) is typically a major international hub known for full-service carriers and frequent transfer traffic, often perceived as a premium, well-equipped gateway. Located about 20–25 km northeast of downtown Singapore, travel to the city center usually takes 30–40 minutes by MRT or 20–30 minutes by taxi depending on traffic; fares can range roughly from SGD 1.50–3.00 for the train and SGD 20–40 for a metered taxi. Changi usually offers extensive lounges, shopping, and transit amenities, making connections comfortable, though its size can mean longer walks between gates. For budget-conscious flyers, low-cost carriers may use nearby dedicated terminals, which can be simpler but less luxurious.

The cost of a one-way flight from Seoul to Singapore ranges from $100 (February 2026) to $196 (May 2026). On average, the ticket price is about $130–$242.
