»»U.S. Airlines Must Rebook About 1 Million Passengers After Snow Storms
The Air Transport Association, a trade group for large carriers, said 15,000 flights were grounded from Feb. 5 in the U.S., the USA Today reports.

The newspaper quoted Air Transport Association spokesman David Castelveter saying: “Those flights would have carried about 1 million passengers, all of whom must be rerouted on other flights. This could shape up to be one of the most significant weather events affecting flight cancellations and passenger travel in decades”.
Airlines say it could take days to rebook the passengers.
David Castelveter explained there is another reason for the high number of cancellations: airlines want to avoid stranding planes on the tarmac.
Darryl Jenkins, an airline consultant said: “Cancellations will become the new norm, rather than take any chance for long delays.” (source)
