Airlines will meet with the Federal Aviation Administration Wednesday to address weeks of delays at Newark Liberty International Airport following air traffic control staffing and equipment issues.

Sunday's incident marks the fourth time in the past two weeks that technical problems have disrupted air traffic at Newark.

The transportation secretary admitted to redirecting his wife through New York's LaGuardia airport but said it was because of Newark’s reliability, not safety.

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.

Duffy laid out an extensive plan to replace the nation’s outdated air traffic control system last week, including installing 4,600 new high-speed data connections and replacing 618 radars, but didn’t put a price tag on the plan other than to say it will cost billions.

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

The Federal Aviation Administration is working on a short-term fix to the problems at the Newark airport that includes technical repairs and cutting flights to keep traffic manageable while dealing with a shortage of controllers.

Newark Liberty International Airport has been at the center of some of these air traffic control issues for the past few weeks. A temporary radar and radio outage set off delays and cancellations that continue to persist.
