IRNA – The average age of the planes of Iran's national flight carrier reduced to about 20 years, said the managing director of Iran Air after her company received two ATR planes on Saturday.

'The average age of the Iranian fleet was 20 years and one month which reduced to 20 after receiving new planes including two ATR turbo-propellers today,' said Farzaneh Sharafbafi.

She said that Iran Air has received 11 new planes and is going to receive 12 more from ATR according to an agreement signed following the nuclear agreement in 2015.

The two ATR planes made jointly by France and Italy landed in Tehran Mehrabad Airport on Saturday.

According to Iran State Aviation Organization, the ATR planes add 140 seats to the aerial fleet of Iran Air.

Following the implementation of the 2015 nuclear deal officially known as the Joint Comprehensive Plan of Action (JCPOA) and removal of anti-Iran aviation sanctions, the deal to buy 100 planes from the French Company Airbus, 80 planes from US-based Boeing and 20 from ATR was signed, nine of which have so far been handed over to the country.

Under the JCPOA, Iran received relief from international sanctions in return for restrictions on certain aspects of Iran's nuclear program.
