A communication issue is creating havoc for flights arriving at New York’s John F. Kennedy International Airport and New Jersey’s Newark International Airport Saturday night as some flights are delayed more than 2 1/2 hours.

A spokeswoman for the Federal Aviation Administration said in a statement that flights at the New York metro airports were delayed due to an “external communications problem” that is affecting area air traffic control facilities. The agency said technicians are working to resolve the issue.

Flights departing from the airports are also being delayed more than an hour.

A spokesman for the Port Authority of New York and New Jersey, which operates both airports, referred a call for comment to the FAA.

Delays were also reported at LaGuardia, Long Island MacArthur, Westchester County and Teterboro airports.

The FAA is encouraging people to check with their airlines to see if their flights are affected.
