Transportation Secretary Sean Duffy explained Wednesday that he recently changed his wife’s flight to avoid the embattled Newark Liberty International Airport — but not because of safety issues.

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.

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

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

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

Experts said while the air system is safe, it is definitely being stressed out — which is why we might see fewer flight options this summer.

Transportation Secretary Sean Duffy plans to reduce the number of flights in and out of the Newark Liberty International Airport for the “next several weeks,” as New Jersey’s largest airport struggles with radar outages and numerous flight delays and cancellations due to a shortage of air traffic controllers.

Newark Liberty International Airport is facing another FAA-imposed ground delay due to staffing shortages, after a telecommunications issue led to delays on Sunday.
