The number of canceled flights to and from Moscow’s Sheremetyevo International Airport rank the highest worldwide as western governments continue closing airspace to Russian aircraft.
One in every five departing and arriving flights from Sheremetyevo have been canceled as of 12:30 p.m. ET Monday, according to data on flight tracking site FlightAware. The airport is the largest in Russia, according to its website.
Russian carrier Aeroflot has canceled one-quarter of its Monday flight schedule and delayed another 10% of flights, FlightAware said.
Europe and Canada have banned Russian flights from entering their airspace, leaving some aircraft to take circuitous routes.
Late Sunday, Aeroflot Flight 111 from Miami to Moscow “violated the prohibition put in place” by Canadian aviation officials.
“We are launching a review of the conduct of Aeroflot and the independent air navigation service provider, NAVCAN, leading up to this violation,” Transport Canada tweeted. “We will not hesitate to take appropriate enforcement action and other measures to prevent future violations."
Aeroflot has now canceled the same flight scheduled for Tuesday.
On Friday, Delta Air Lines announced it was ending its codeshare booking partnership with Aeroflot. Delta said it would re-accommodate passengers on the handful of flights impacted by the move.
