The United States, according to the WSJ, is going to announce today that it will follow what the EU and Canada already did last week and close its airspace for Russian airlines.
Russia on Monday retaliated tit-for-tat and banned airlines from 36 counties from using its airspace, especially affecting flights between Europe and North Asia that tend to fly over Siberia.
