Hundreds of flights delayed or canceled at Logan Airport after nationwide ground stop

Flights at Logan Airport in Boston are resuming hours after a nationwide ground stop was issued by the FAA on Friday. Hundreds of flights have been delayed or canceled. 

Planes were lined up on taxiways and runways at Logan during the ground stop that went into effect Friday afternoon. The FAA lifted it at 8:15 p.m.

The FAA and White House said the issue appeared to be caused by a "telecommunication outage."  

"As flight operations gradually return to normal, some delays may continue," Logan Airport operator Massport said Friday night. "We encourage passengers to check directly with their airline for the latest flight information. Thank you for your patience and understanding."

According to FlightAware, there are 292 total delays and 335 cancellations at Logan Airport as of 9 p.m.  

JetBlue said it canceled all remaining flights Friday, with the exception of Europe-bound flights from Logan and JFK Airport in New York.

At a news briefing Friday night, U.S. Secretary of Transportation Sean Duffy attributed the rare nationwide ground stop to outdated air traffic control technology and routers overloaded by data.

"I've been briefed on the FAA's nationwide ground stop and am in touch with Massport about what it means for people flying in and out of Massachusetts," Gov. Maura Healey said in a statement. "We're working to get answers from federal officials and will share updates as soon as we have more information."  

Massport said the FAA permitted some transatlantic flights to depart Logan Airport during the ground stop. A WBZ-TV photographer's flight to Germany to cover the New England Patriots game took off at about 5 p.m. after an hour delay.
