Scott Kirby, the CEO of United Airlines, joins TODAY to discuss the issues plaguing Newark Liberty International Airport as air traffic control towers across the country are seeing staffing shortages.

Several times over the last year, Newark controllers lost radar or radio service, leaving them unable to talk with planes they were tracking.

A third air traffic control outage in just weeks at Newark Airport is raising concerns about aging infrastructure at major aviation hubs nationwide.

United Airlines executives are trying to reassure their customers it is safe to fly at Newark Liberty International Airport​, despite all the recent problems.

Over the past two weeks, several equipment outages at the Philadelphia-based air traffic control center that guides planes to and from Newark Liberty International Airport, have raised questions on just how safe it is to fly at one of the nation’s busiest airports.

Staff shortages and equipment failures at Newark Liberty International Airport have raised safety concerns in recent weeks.

Newark airport's been plagued with issues that have travelers like me concerned about safety. It's not dangerous, but delays are a bigger concern.

Moving air traffic controllers means retraining them on the quirks of a new facility, and the process can take years.

Airline chief executives are poised to work with US aviation officials to throttle back more Newark airport flights, a fix that may ease short-term safety concerns but won’t solve long-term problems.
