The plane was then towed to a gate with passengers on board, she said.
The Port Authority of New York and New Jersey, which operates the airport, said 35 people were aboard the plane.
The airport temporarily suspended operations for domestic and international flights because of slick runways, though it remained open. Flights are still operating at other New York City-area airports, including at LaGuardia and Newark Liberty, the Port Authority said.
The landing came two days after a major snowstorm dumped a half foot of snow in New York City, forcing the cancellation of hundreds of flights and stranding passengers both in the city and throughout the country who were heading to New York.
The Delta Connection flight by Endeavor Air originated in Toronto. Endeavor Air was formerly Pinnacle Airlines.
Update, 10:53 a.m. EST: Flights have now resumed.
