The Biden administration wasn’t quite ready to let the federal transportation mask mandate lapse, out of fear they’d look stupid if Covid-19 cases surged again. But they know the mandate is on its last legs. Every state is eliminating its indoor mask mandates (or has already done so). Even if cloth masks were effective against the Omicron variant, this mandate would do very little on its own.
The federal mask mandate for commercial airlines, airports, trains and buses was set to end March 18. It will be extended through April 18. That one month extension, announced a mere 8 days before the rule would have lapsed, is the shortest extension yet. And, barring unforeseen events, is likely to be the last.
