A power outage at New York City's LaGuardia Airport caused at least 100 flight cancellations Friday.
Steve Coleman, a spokesman for the Port Authority of New York and New Jersey, which runs the region's airports, said dozens of flights were canceled and at least five were delayed at the Delta terminal after power went out at 4:30 a.m. Friday.
Coleman said Delta's communication system came back around 9:45 a.m. and flights were expected to follow. Residual delays were expected into late morning or early afternoon.
Delays of about 2 hours have dropped to about 16 minutes.
The outage also affected the jet bridges that lead from the terminal to the airplane. That power was restored at 8:30 a.m.
The outage occurred when a contractor accidentally cut two electric feeders that serve the terminal. There were no injuries and electrical staff are working on repairs, according to the Port Authority.
US Airways, which uses the terminal, was not affected.
