The airlines that operate at the Billings Logan International Airport began requiring that all passengers wear a face mask from the check-in process until they deplane. The order comes from Delta, United, Frontier, Alaska and American. Director of Aviation and Transit, Kevin Ploehn, said, “  For the future, this will be the new normal, and frankly, if the airlines are going to entice folks back into the sky they need to do this so people can feel safe.”
