DALLAS (AP) — More than 700 U.S. flights were canceled and about 4,400 were running late on Tuesday as a winter storm swept across the Northeast.
Adding to travelers' woes: United Airlines experienced problems with its computer system used to check in passengers, print boarding passes and get baggage tags.
By early evening, about 650 United flights and another 1,000 flights on regional affiliate United Express had arrived late or were behind schedule, according to tracking service FlightAware.com. United said that most of the delays were due to the computer glitches.
Travelers took to Twitter to complain to United. Spokeswoman Jennifer Dohm told The Associated Press that the airline fixed the problem and was working to get passengers to their destinations. Glitches also led to widespread delays at United in early 2012, when the computer systems of United and Continental Airlines were combined after their merger.
United wasn't the only airline struggling to stay on schedule Tuesday. Southwest had more than 1,100 delays, according to FlightAware.
