Yesterday, when a federal judge from Florida lifted the requirement for face masks on transportation, we slowly saw the dominos fall and most forms of transportation do not require them anymore.
Airlines that don't require masks: American Airlines, Southwest, Delta, JetBlue, Spirit, and United Airlines.
Both Lyft and Uber have lifted their mandate for both passengers and drivers. Amtrak no longer requires any masks of any kind. So enjoy your mask free world out there, don't be surprised if at anytime this changes if the levels of COVID-19 start to spread rapidly again. Be safe out there, people!
