The Port Authority blamed "cascading" issues that included the large numbers of holiday travellers, difficulties in baggage handling and staff shortages.
Worldwide flights are coming into JFK Airport's Terminal 4 after they were shut down earlier Sunday due to a water pipe break that has delayed flights all day. Now the Port Authority is launching an investigation into how a water pipe that feeds the sprinkler system could burst and cause such huge problems.
"A surge in flights at JFK Airport, produced by the rescheduling of delayed flights, combined with the effects of the winter storm, which severely disabled equipment, has resulted in terminal operators and airlines experiencing delays in getting planes and their passengers into their gates", the Port Authority said in a statement.
Power in the affected area of the terminal was temporarily shut off for safety reasons.
"Due to a water main break at #JFK Terminal 4 there are flight delays", the airport tweeted Sunday.
More delays have been added Sunday to the storm-related aftermath the already beleaguered airport is working to recover from.
"Passengers who have already arrived are being deplaned and taken to other terminals for processing", the spokesman said in a statement.
The terminal was accepting no global arrivals for much of the afternoon, but around 7:45 p.m. ET, the airport said it was resuming operations. Maintenance crews were deployed to mop up the west end of the terminal, which saw about three inches of flooding, according to a Port Authority spokesman. "There has been no impact on departures and [the airport shuttle] as far as we know".
Kuwait Airways flight 118 was involved in a minor collision on the tarmac at New York City's John F Kennedy Airport on Saturday as it prepared to head back to Kuwait City just after midnight on Sunday.
