Istanbul Airport (IST) is Turkey’s main international hub and typically handles the majority of long-haul and premium carriers, so fares can be competitive for global connections. Located about 40–45 km northwest of the historic city center, journey times by taxi or rideshare usually range from 35 to 60 minutes depending on traffic, with fares commonly higher than for inner-city transfers; the Havaist and municipal airport buses offer direct routes in roughly 45–75 minutes for a modest fee, while the new metro link can be faster at peak times. Pros: modern terminals, many lounges and transfer facilities; Cons: distance from central neighborhoods and variable road congestion can add time and cost to transfers. Sabiha Gökçen International Airport (SAW) serves as Istanbul’s main budget and secondary international gateway, often favored by low-cost and some regional carriers and typically offering lower-priced options for point-to-point travel. It sits on the city’s Asian side, about 35–45 km from Taksim and the historic peninsula, with travel times by taxi or rideshare commonly between 40 and 60 minutes; express airport buses and Havabus services connect to central districts in roughly 60–90 minutes for a modest fare, and a commuter rail/metro extension is increasingly improving connections. Pros: often cheaper flights and less congestion inside the terminal; Cons: longer transfers to some European-side destinations and fewer long-haul carrier options compared with the main hub.

Tehran is served mainly by two airports with distinct roles. Imam Khomeini International (IKA) is the primary international gateway and usually handles long-haul and most scheduled foreign carriers, while Mehrabad (THR) typically functions as Tehran’s domestic and regional hub with many budget and national airlines. IKA sits roughly 40–60 km southwest of the city center; travel options include airport shuttles or long-distance buses (about 40–90 minutes depending on traffic) and taxis or rideshares with fares that can vary widely. Mehrabad is much closer, around 8–15 km west of central Tehran, reachable by metro, local buses, or short taxi rides in 20–45 minutes. Pros: IKA provides more international services and modern facilities; Mehrabad can be quicker for domestic connections. Cons: IKA’s distance can make transfers slower and more affected by road congestion, while Mehrabad may feel crowded at peak times.

In different months, ticket prices from Istanbul to Tehran vary: minimum — $85 (February 2027), maximum — $285 (July 2027). Typically, the flight costs $118–$135.
