At a House committee budget meeting, Transportation Secretary Duffy explained why he switched his wife's flight away from Newark after the airport had several tech and staffing issues

With summer travel season approaching, the crisis at the New Jersey airport could mean weeks, if not months, of misery for travelers.

The shortage on Monday forced the F.A.A. to delay flights to the busy airport for up to nearly seven hours, the latest problem to plague the airport.

An air traffic controller said the airport was unsafe. Days later, Transportation Secretary Sean Duffy moved his wife’s flight.

The safety nightmare continues at Newark Liberty International Airport, where all air traffic control will be manned by just one fully qualified person during its busiest time on Monday night local time,

The air traffic control system has been under immense pressure for years given the persisting staffing shortages, outdated technology and underinvestment in critical infrastructure.
