It was chaos earlier today at New York’s John F. Kennedy International Airport, as there was a massive flood at Terminal 4, all caused by a frozen water pipe bursting.

Terminal 4 is Delta’s main home at JFK, but also houses several international airlines including Emirates, EgyptAir, El Al, Etihad Airways, Virgin Atlantic, Swiss, and Singapore Airlines.

With this flood, the terminal’s custom/immigration was shut down, which forced many diversions of international flights as passengers weren’t  able to clear customs and immigration this afternoon. Delta had even issued a waiver for those passengers traveling to/from/through JFK today.

Delta flight 787 scheduled from Cancun to New York’s JFK, diverted to Atlanta as a result of the flood which caused the arrivals hall including customs/immigration to shut down today.

Per CNN

A water main break flooded a baggage claim area at JFK International Airport in New York on Sunday afternoon, compounding flight cancellations and other headaches caused by the cold wave.

Water flowed into Terminal 4, soaking stranded travelers’ luggage and forcing a partial evacuation of the terminal, the major arrival point for international travelers. Incoming flights to Terminal 4 were shut down for several hours.

Up to 3 inches of water formed in the arrivals and customs inspection areas of the terminal and then flowed outside onto a roadway, which was closed because of icing, Port Authority Executive Director Rick Cotton said at a news conference. He said the arrivals area and customs office should reopen within several hours.
