Airlines in the United States began to resume flights after the lifting of restrictions

U.S. airlines began resuming flights after the restrictions were lifted, NBC reported.

United Airlines said that despite the cancellation of flights, the implementation of some of them is still planned. "United is resuming operations, including operating some flights on Friday night," it said. “Thank you for your patience as we work to restore a full schedule,” it added.

Delta Air Lines also announced the resumption of flights. "Delta is safely restarting flights as the Federal Aviation Administration's (FAA) nationwide departure ban has been lifted," the company said in a statement. “Although aircraft have already begun to depart for flights, it will take time to restore full operation, including the redeployment of aircraft and crews,” it said.

Transport Secretary Sean Duffy said it may take some time to restore normal air traffic. "The process will be slow," he said, urging passengers to check with their airlines. "It all depends on whether there are crews - pilots and flight attendants - ready to perform your flight," he explained.
