Hundreds of flights at NYC-area airports were grounded for more than six hours Monday due to an FAA-issued ground stop that was the result of issues connected to TRACON, the air traffic control system in Philadelphia.⁠ ⁠ Flights in Philly and at LaGuardia Airport resumed in the afternoon, but at Newark Airport alone, more than 400 departing and arriving flights had already been scrapped by 4 p.m.⁠ ⁠ Transportation Sec. Sean Duffy blamed an Amtrak construction crew for the delays and cancellations, saying they accidentally cut into a fiber line in New Jersey, forcing the FAA to pause flights in the northeast. Repairs could take hours, according to officials.⁠ ⁠ #nbc4ny #travel #newark #nyc #airtravel
