American Airlines said this week that all customers over the age of 2 years will be required to wear face coverings while in airports and during flights, joining other carriers, including United Airlines, that have recently added an in-terminal mask mandate.

The new rule becomes effective next week and requires passengers to wear face coverings from the time they enter their departure airport until they exit their arrival airport. This updated policy includes all areas of the airports at which American operates, including Admirals Club lounges.

“According to the Centers for Disease Control and Prevention, one of the best ways we can slow the spread of COVID-19 is to wear a face covering,” said Alison Taylor, chief customer officer for the carrier. “Customers and team members have been clear that they feel more safe when everyone is wearing a face covering. In light of this important feedback, we are expanding and enhancing our requirements onboard and at airports.”

The only time face coverings may be removed at the airport or during flights is when the customer is eating or drinking. Those unwilling to comply with this face covering requirement at any time during their journey may be barred from future travel for the duration of this face covering requirement, the airline said.
