(Reuters) -New York City's John F. Kennedy International Airport (JFK) will reopen its Terminal 1 for limited operations on Saturday, after it remained closed on Friday due to an electrical power outage.
"Contingent on the completion of repairs and testing, we anticipate the start of limited operations at Terminal 1 on Saturday," the Port Authority of New York and New Jersey, JFK's owner, told Reuters in a statement on Friday.
Terminal 1 represents 5% of all JFK scheduled passenger flights, and of today's 64 scheduled Terminal 1 arrivals and departures, 39 have been canceled, the Port Authority said.
The outage, disrupting inbound and outbound flights at one of the world's busiest airports, began after an electrical panel failed and caused a small, isolated fire that was immediately extinguished overnight on Thursday.
The terminal serves several international carriers, including Air France and Lufthansa.
Amongst other disrupted flights, the outage forced a JFK-bound Air New Zealand airplane to return to Auckland about eight hours into a trip, returning to its departure point about 16 hours after the flight began.
Air New Zealand said "diverting to another U.S. port would have meant the aircraft would remain on the ground for several days, impacting a number of other scheduled services and customers." The airline said all passengers on the flight have been accommodated on flights leaving Auckland.
The Federal Aviation Administration declined to comment about the disruption to air travel.
As of 1:30 p.m. on Friday, JFK's website showed 120 inbound and outbound flights were either delayed or canceled at the airport. About half were international flights.
In all, about 3% of flights at the airport had been canceled on Friday, according to flight-tracking website Flightaware.com.
"We apologize there are no new updates at the moment. Please continue to check with your air carrier for flight status," JFK said in a tweet on Friday afternoon.
The Port Authority of New York and New Jersey, JFK's owner, was working with the terminal's operator to restore flight operations as quickly as possible, it said earlier.
JFK said it was working to accommodate affected flights using some of the other four terminals at the airport.
