Just look at all the videos when it was announced. The majority of the people on board the various planes immediately cheered. Even the liberal cities like Boston and San Francisco have dropped the mandates for the local buses and subway systems. To the best of my knowledge, at least in my area, the only places still mandating them are New York city And CT transit buses and Commuter rail in Connecticut. Even Amtrak has dropped the mask mandate.
CTA in Chicago still requires face diapers. Funny thing is SEPTA in Philly does not, but Philly has an indoor mask mandate.
