A court (a trump federal judge Iiuc) struck down the airline/transportation mandate. The cdc can still appeal but it will be a tough slog given the airlines, airport authorities, Amtrak and tsa all within a matter of hours ended the mandates and in the case of private companies declined to do voluntary ones. Reports of people cheering mid flight and masking collapsing. The Biden admin might still decide to appeal but given the surprising speed of collapse they’d be swimming against the public. Might portend the end of masking period but too soon to tell (word is Hawaii for example may move to try and reinstate for its flights)
