Ongoing mask mandate for travelers: 'It will be enforced, period'

Travel is a big exception for new mask guidance in the United States, and the airline industry says it will continue to strictly enforce mask use.

(CNN) — Travel is a big exception for new mask guidance in the United States, and the transportation industry says it will continue to strictly enforce mask use. The head of the largest association of flight attendants said "there should be no confusion" about new Centers for Disease Control and Prevention guidance saying fully vaccinated Americans no longer need to wear masks indoors, but still need to wear masks when traveling. "This doesn't include transportation," Association of Flight Attendants President Sara Nelson told CNN. "There's a mask order in place and it will be enforced, period."
