Istanbul is served by two main airports with distinct roles. Istanbul Airport (IST) is the city’s international flagship and a major global hub for long-haul and transfer traffic, typically hosting full-service carriers and many international routes; fares can be mid-to-high compared with regional options. It sits about 35–45 km northwest of the historic center; metro, express bus and taxis connect it to the city in roughly 35–60 minutes depending on traffic, with public transit fares usually modest and taxis noticeably more. Pros: extensive facilities, many connections and a modern terminal; cons: longer transfer times to central districts and potentially higher ground-transport costs. Sabiha Gökçen International Airport (SAW) operates as Istanbul’s budget- and low-cost-oriented airport on the Asian side, commonly used for domestic flights and many European low-cost services; ticket prices can often be lower than from the main hub. It lies about 35–50 km southeast of Sultanahmet; options include shuttle buses, public buses, and taxis that typically take 45–75 minutes depending on traffic, with economy fares on buses and higher taxi fares. Pros: convenient for Asian-side residents and cheaper carriers; cons: fewer long-haul connections and sometimes longer trips across the Bosphorus to European districts.

Seoul is served primarily by two airports with distinct roles. Incheon International (ICN) is the city’s major international hub, handling most long-haul and full-service carriers and typically offering a wider range of lounges, shops and transfer facilities; it sits about 48 km west of central Seoul, with the AREX express train taking roughly 43–55 minutes to downtown (fare ranges roughly KRW 4,500–9,000 depending on service) and airport buses or taxis often taking 60–90 minutes depending on traffic. Gimpo Airport (GMP) functions as a closer gateway for domestic flights and select short-haul international routes, usually served by budget and full-service Korean carriers; it’s about 15 km from the city center and reachable by metro in around 20–30 minutes (low fares), or by taxi in 20–40 minutes. Pros: Incheon is well-equipped for international connections and comfort, while Gimpo is convenient for quick access to Seoul. Cons: Incheon’s distance can add travel time and cost, and Gimpo can be busier with fewer international amenities.

The minimum one-way ticket price from Istanbul to Seoul is $272 (December 2025), while the maximum is $411 (June 2026). On average, a ticket costs $342–$343.
