Tehran - The Iranian airline wants to increase its existing order with Boeing if the US government doesn't put obstacles.

The Aseman Airlines' fleet is more than 25 years old on average, but it could change soon. In February 2017, the airline announced it would lease seven Airbus A320neo. In May, it signed a letter of intent to buy 30 Boeing 737 Max, which was converted then into a firm order in August.

The investment company Atieh Saba Investment, the largest shareholder of Iran Aseman, is interested in buying another 30 Boeing jets, according to the Iranian news agency Irna.

The government of Donald Trump repeatedly stated that they consider to tighten the sanctions against Iran again. The existing order had so far no problem. The Boeing 737 Max(s) should be delivered over the next two years.

The current fleet of Iran Aseman consists of 33 aircraft, including six Airbus A320-200s, one A340-300, five ATR 72s, four Boeing 727-200s, three 737-400s and 14 Fokker 100s. The airline serves 44 destinations in eight countries.
