Alaska Air Group Inc.’s Alaska Airlines announced more stringent requirements for cloth masks and face coverings in an effort to stop the spread of the COVID-19 virus, saying “no mask, no travel, no exceptions.” The air carrier said everyone age 2 and older must wear a face covering, over their nose and mouth, at all times when at the airport or onboard Alaska Airlines aircraft, “with no exceptions.” The company said it a customer is unwilling or unable to wear a mask “for any reason while at the airport,” they will not be permitted to travel. If a passenger refuses to wear a mask after boarding, the company said they will be suspended from future travel. “We all need to look out for each other during this health emergency, and the best way we can do that — and prevent the spread of the virus — is to simply wear a mask or face covering when we’re around each other,” said Max Tidwell, vice president of safety and security. “Our tougher policy shows how important this issue is to us and our guests. If you don’t wear a mask, you won’t be flying with us.” The stock was unchanged in premarket trading.
