Most airlines were giving up on flying in and out of New York, Boston and other airports in the Northeast Friday as a massive storm threatened to dump snow by the foot on the Northeast.
Airlines were generally shutting down operations in the afternoon at the three big New York-area airports as well as Boston, Providence, Portland, Maine, and other Northeastern airports. They're hoping to resume flights on Saturday.
Flight-tracking website FlightAware said airlines have canceled more than 4,000 flights on Friday and Saturday in advance of the storm.
Many travelers were steering clear of that part of the country altogether. Airlines waived the usual fees to change tickets for flights in the affected areas.
Airlines began canceling Saturday flights on Friday, hours before the storm was due to hit, said Daniel Baker, CEO of FlightAware. "That's when the meteorologists start to have reliable predictions and the FAA holds conference calls to discuss which airports are shutting down," he said.
Airlines are also at the mercy of mass transit in each city they fly to. They'll often wrap up flying around the same time that trains and subways begin shutting down, he said.
Airlines try to get ahead of big storms by canceling flights in advance rather than crossing their fingers that they can operate in bad weather.
Storms like this one jam up airline call centers, so airlines are increasingly automating the process of rebooking passengers.
Delta (NYSE:DAL) is rolling out software it calls "VIPER" -- Virtual Inconvenienced Passenger Expedited Reprotection -- to find a replacement flight for passengers whose flights have been canceled.
As any frequent traveler knows, during a bad storm, the fastest route from, say, New York to Minneapolis may be through Atlanta, or Salt Lake City. Airline workers are adept at finding such routes manually. The new Delta system looks for such "creative routings" automatically and sends a message to the traveler telling them about their new flight, Delta Air Lines CEO Richard Anderson said on an employee hot line message last week.
"We need the ability to use automation to figure out for our passengers the quickest and fastest way to (reaccommodate) them on Delta or other carriers," he said. "Our goal is to get them to their destination as promptly as possible."
The snow was snarling air travel in Canada, too, with 240 flights canceled on Friday at Pearson International Airport in Toronto. Environment Canada senior climatologist David Phillips said Toronto hasn't seen a snowfall exceeding 5 inches since Dec. 19, 2008. The current storm was expected to dump up to 11 inches of snow as it moves along.
