Two of the biggest airports serving New York -- John F. Kennedy and Newark Liberty International -- are open today.
The first passenger flight to JFK arrived from Long Beach, Calif., at 7:04 a.m. Wednesday. The JetBlue flight carried 150 passengers.
The first flight into Newark, N.J., was a FedEx plane that landed at 7:12 a.m.
Port Authority of New York and New Jersey spokesman Ron Marsico says the two airports reopened "on a very limited operational schedule." He urged passengers to call their carriers before heading to the airports.
Some terminals at Newark had lost power during the superstorm but electricity returned on Tuesday.
New York's LaGuardia Airport remains closed. Authorities are assessing the impact of the storm on the airport.
For travelers flying out of Denver International Airport, officials suggest calling the airline to check for specific delays and cancelations.
