NEW YORK (CBSNewYork/AP) — Flights have resumed at LaGuardia and John F. Kennedy International airports a day after weather-related suspensions.

The Port Authority of New York and New Jersey said flights at JFK resumed around 7 a.m. Friday, but urged travelers to check with their airlines before heading to the airport.

Flights were suspended at JFK due to strong winds and whiteout conditions caused by a winter storm that has pummeled the East Coast with heavy snow and hurricane-force winds.

A Singapore Airlines flight bound for JFK was diverted to Stewart Airport in Orange County instead, because of the weather.

Air traffic suspensions at LaGuardia Airport were also lifted, but authorities advise passengers to contact their airlines regarding specific flights.

Officials are also encouraging travelers to use public transit because heavy passenger volumes are expected as operations resume.

Newark Liberty Airport did not suspend flights, though it also experienced massive delays and cancellations as a result of the storm. The airport Friday was experiencing 2-hour delays for arriving flights due to wind.

The flight-tracking site FlightAware reports nearly 5,000 flights were canceled across the United States. Those flights include more than two-thirds of flights in and out of New York City and Boston airports.
