Iran Air, the country’s national carrier, plans to resume its flight operations on April 22 after a 50-day interruption, The Caspian Post reports, citing Iranian media.

The first scheduled flight will take place on Wednesday, operating from Tehran to Mashhad.

Iran had already partially resumed air traffic from some of its main airports earlier.

The first passenger aircraft to operate after the reopening of Iranian airspace flew from Oman to Iran on April 18.
