Iran Aseman Airlines has signed a memorandum of agreement to purchase 30 Boeing 737 Max aircraft at a list price of $3 billion.

The deal includes purchase rights for 30 additional 737 Max aircraft.

Deliveries will begin in 2022, says Boeing.

The airframer says it began negotiating the aircraft deal with authorisation from the US government, following the signing of the Iran nuclear deal in 2015. It adds that it will look to the Treasury's office of foreign assets control for approval to act on the transaction.

US President Donald Trump has criticised the Iran nuclear deal, and it is not immediately clear if his administration will block the planned Boeing order.

"Boeing continues to follow the lead of the US government with regards to working with Iran’s airlines, and any and all contracts with Iran’s airlines are contingent upon U.S. government approval," says the airframer.

Iran Aseman operates a fleet of 29 aircraft, including three Boeing 727-200s and two 737-400s ranging from 25 to 37 years old. It also has six Airbus A320s and one Airbus A340 among other aircraft types.
