Alaska Airlines threatens unmasked fliers with yellow cards

In soccer, a misbehaving player will receive verbal warnings from referees, and if the bad conduct continues, he or she will be handed a yellow card – which means “this is your final warning.” One more misstep after that and the miscreant gets a red card and is ejected from the match.

Starting early in July, Alaska Airlines will borrow that system for flight attendants to use in enforcing the airline’s in-flight face mask policy.
