Nobody likes being the mask police, so just do everyone else a favor and do it.
The Centers for Disease Control and Prevention (CDC) and Department of Health and Human Services (HHS) have issued an order mandating masks at airports and other transportation hubs starting today through April 18, 2022.
Though most airlines already have a mask policy in place, this isn't relegated to air travel anymore. It extends to all forms of travel where people may congregate to board a moving vehicle.
The only exemptions are for children under the age of 2, and those with disabilities that prohibit them from wearing a mask safely under the Americans with Disabilities Act.
(Some airlines also have been flexible regarding the age of children, though this is no longer something up to their discretion.)
The face mask mandate essentially extends this to trains, buses, boats, subways, inside airports and other similar types of places.
For the record, so that there is no confusion, this is how the CDC is defining it:
Transportation hub means any airport, bus terminal, marina, seaport or other port, subway station, terminal (including any fixed facility at which passengers are picked up or discharged), train station, U.S. port of entry, or any other location that provides transportation subject to the jurisdiction of the United States.
Remember: The faster that we are all part of the solution, the sooner that we can move on with the rest of our lives.
