Delta Air Lines estimates that Hurricane Irene caused its profit to fall by $15 million, and US Airways said the storm hit its operating income by up to $10 million. The storm forced airlines to cancel thousands of flights, but industry experts say it could have been worse. "With the exception of the New York airports, this storm was not as bad as a typical big blizzard," said Robert McAdoo, an analyst at Avondale Partners. "Once the storm passes, there's no snow to scoop, no planes to de-ice. It goes back to normal pretty quickly."
