Iranian domestic carrier Zagros Airlines signed a memorandum of understanding (MoU) to buy 28 new Airbus (AIR.PA) planes, comprising 20 A320neo jets and eight A330neo aircraft, while Iran Airtour signed an MoU for 45 A320neo aircraft, Reuters reported.
Iran has stepped up its orders of planes after anti-Tehran sanctions were lifted following the 2015 nuclear deal between Tehran and world powers.
Airbus said the MoUs were contingent upon all necessary approvals, including from the US Office of Foreign Assets Control.
Airbus sales chief John Leahy said he expected the US approvals within the next couple of months.
Airbus said it would continue to act in full compliance with the Iran nuclear deal, also known as the Joint Comprehensive Plan of Action (JCPOA), and associated rules.
Iran Air has ordered 100 planes from Airbus and 80 from Boeing (BA.N).
Iran and the Group 5+1 (Russia, China, the US, Britain, France and Germany) reached the 159-page nuclear agreement in July 2015 and implemented it in January 2016.
