“We learned about it essentially when you called,” said Adam Brandolph with the Port Authority.

But it turns out it won’t be a big deal for the airport or the Port Authority.

“Port Authority passengers and our operators have been required to wear masks while on vehicles and while waiting at stops with others and at our downtown service centers,” said Brandolph.

The Port Authority admits they’ve had problems with some passengers and drivers who weren’t wearing masks. A federal mandate gives them more power to police it. And at the airport, you can’t get on a flight without a mask.
