PHILADELPHIA (AP) -- More than 600 commercial flights have been canceled so far and nearly 2,000 others are running late as another winter storm sweeps across the Northeast U.S., officials said Tuesday.
Adding to travelers' difficulties Tuesday, United Airlines is experiencing problems with its fleet-wide passenger-service computer system. By midday, 350 United flights had been delayed, according to tracking service FlightAware.com.
It was not immediately known how many flight disruptions were due to the computer outage. United did not immediately provide details.
Snow and ice are also snarling air traffic in the Northeast -- where more than 100 departures have been canceled at Newark Liberty Airport in New Jersey, and dozens more in New York City and Philadelphia.
Several storms have slammed travelers in the eastern U.S. so far this winter, where airlines have canceled more than 75,000 domestic flights since Dec. 1 -- the most since the government began keeping records in winter 1987.
