Tehran is served by two main airports with distinct roles. Imam Khomeini International Airport (IKA) is the primary long-haul and international gateway, handling most intercontinental carriers and full-service airlines; it’s often perceived as the pricier option for long-distance flights. Located about 45–60 km southwest of central Tehran, transfer times can be 45–90 minutes by taxi or dedicated airport bus, with fares typically ranging from modest bus fares to mid-range taxi rates. Mehrabad Airport (THR) mainly handles domestic and regional flights, served by Iran’s major carriers and budget-friendly operators; it sits roughly 8–12 km west of the city center and is reachable in 20–40 minutes depending on traffic. Pros: IKA offers modern international facilities and more onward connections; THR is closer to downtown and convenient for quick domestic hops. Cons: both can be affected by heavy traffic to/from the city, and transfer times may vary significantly by time of day.

Bangkok is served by two main airports with distinct roles. Suvarnabhumi (BKK) is the city’s international gateway and full-service hub, typically handling long-haul and many carrier-network flights including major global and regional airlines; it’s about 30–40 km east of central Bangkok, with train, taxi and express bus options taking roughly 25–60 minutes depending on traffic and chosen service, fares varying from modest train fees to higher taxi or private transfer rates. Don Mueang (DMK) functions mainly as a low-cost and domestic-focused airport, often used by budget carriers and regional flights; it sits approximately 20–25 km north of the city center and is connected by shuttle bus, taxi and commuter rail, usually slightly quicker in light traffic but with fewer premium amenities. Pros: Suvarnabhumi offers broader international connections and more services, while Don Mueang can be cheaper and closer for some neighborhoods. Cons: both can be affected by Bangkok traffic for taxis, and transfers between the two airports require extra planning.
