Mahan Air operated the first Tehran-Moscow flight on 28 April 2026 after a 60-day suspension tied to the war, with Sunday, Tuesday and Thursday service resuming in both directions. Iranian state news agency Mehr News reported the resumption from Imam Khomeini International Airport.
Mahan Air is an Iranian privately owned carrier the US Treasury sanctioned in 2011 for moving IRGC (Islamic Revolutionary Guard Corps) materiel and personnel; the airline has run the Tehran-Moscow rotation as a primary corridor for both civilian transit and dual-use cargo since the 2018 reimposition of US secondary sanctions. The 60-day suspension that the Tuesday flight broke was the longest interruption since the route opened to scheduled service. Three-times-weekly service in both directions implies six flights weekly across the route, the operating tempo Mahan ran before 28 February.
The resumption arrives one day after Abbas Araghchi's confirmed meeting with Vladimir Putin in St Petersburg , and inside the same week Russian Il-76 transport aircraft were tracked into Mehrabad and Bandar Abbas at high tempo . The Pentagon assessed the China-Russia support pattern as actively compounding the war on that 27 April reporting; the Mahan resumption normalises a civilian-coded version of the same corridor without any signed US instrument covering it. The Treasury's only Russia-Iran asymmetry on the books is the 19 April day OFAC issued sanctions wind-downs on Russian-linked entities while signing nothing on Iran, an asymmetry Senator Lisa Murkowski's unfiled AUMF does not address. Russian airspace authorities cleared the slot allocations for the resumption between Putin's reception of Araghchi on 27 April and the Tuesday departure, a turnaround that suggests the diplomatic trip carried operational instructions on logistics restoration alongside the joint statements.
The corridor is being reopened in real time on the same Tuesday the War Powers Resolution clock runs into its final 24 hours.
