Istanbul to Tehran Flights

A nonstop flight from Istanbul to Tehran typically takes around 3 to 3.5 hours, depending on weather conditions and air traffic.

Flights to Tehran depart from both of Istanbul’s international airports: Istanbul Airport (IST) and Sabiha Gökçen Airport (SAW). The departure airport depends on the airline you choose.

For international flights, it’s recommended to arrive at the airport at least 3 hours before departure. This gives you enough time for check-in, baggage drop, security screening, and passport control.

Several carriers offer direct flights on this route, including: Turkish Airlines, Pegasus Airlines, AnadoluJet, Iran Air, Mahan Air, Qeshm Air.

In many cases, round-trip fares are cheaper than buying two one-way tickets, as airlines often offer discounted prices for passengers booking return flights together.

Budget-friendly airlines like Pegasus Airlines and certain charter flights usually offer the cheapest fares. Some Iranian carriers—such as Qeshm Air and Iran Airtour—also tend to provide more affordable prices compared to major international airlines.
