DENVER — For the first time in two years, masks are coming off at the Denver International Airport. The move comes after a federal judge in Florida ruled the national mask mandate covering airplanes and other public transportation exceeded the authority of U.S. health officials. The mandate was set to expire May 3.Following the judge’s decision, the chaos of airport travel was doubled for travelers at the Denver International Airport (DEN). “It’s contradicting,” said Sunny Wilson, who was traveling home to Denver.
