Its main home bases are Tehran Imam Khomeini International Airport and Mehrabad International Airport. Mahan Air is affiliated with the Quds Force of Iran's Islamic Revolutionary Guard Corps.

Mahan Airlines was banned between 2019-2020 from Germany, France, Italy and Spain due to its involvement with the Maduro government in Venezuela and the Assad regime in Syria. In 2024 the airline was sanctioned by the European Union for transporting weaponry to Russia during the Russo-Ukrainian War. It was also suspected of transferring money to Hezbollah, in Lebanon. The airline is also sanctioned by the United States.
