Technicians have repaired data lines that failed at a key regional air traffic control center, and all major airports in the New York area began resuming operations after hundreds of flight cancellations rippled through the Northeast. Transportation Secretary Sean Duffy said in an online post that primary and backup telecom lines were fixed by Monday evening, allowing affected airports to resume operations. But he said significant delays were expected to continue through the rest of the evening. Hundreds of flights were canceled at the Newark, LaGuardia, Kennedy and Philadelphia airports due to the technical problems.
