The US government is about to announce a ban on Russian flights from US airspace following similar actions by the European Union and Canada, government and industry officials told Reuters.
The exact time is not clear, but it is expected within the next 24 hours, sources said.
Late Tuesday, United Airlines said it had temporarily suspended flights over Russian airspace, joining other major US carriers that took the step after Russia’s invasion of Ukraine.
The White House, which declined to comment, has held extensive talks with US airlines in recent days.
In recent days, United have continued to fly over Russian airspace to operate some flights to and from India. Delta Air Lines, American Airlines and United Parcel Service confirmed this week that they have suspended flights over Russia.
FedEx on Tuesday did not respond to emails asking if it had stopped flying over Russia.
United has canceled two flights to India on Tuesday and Wednesday as it assesses how it can continue to operate on a different route that does not use Russian airspace.
White House officials have asked in private whether the move would harm U.S. supply chains or have other negative consequences, sources told Reuters.
