The U.S. is closing its airspace to Russian operators, following suit after a slew of allies did the same in the past three days.

President Biden announced the move at Tuesday’s State of the Union address.

“Tonight I am announcing that we will join our allies in closing off American airspace to all Russian flights, further isolating Russia and adding an additional squeeze on their economy”, - Biden said.

Russia is expected to respond in kind, banning U.S. operators from its massive airspace, just as it has done for the more than 35 countries, including the entire European Union and Canada, that have already banned Russian operators.
