NEW YORK (AP) — United Airlines said Superstorm Sandy cut its October revenue by about $90 million as it was forced to cancel almost 5,300 flights.

That’s nearly an entire day’s worth of United’s schedule lost. It runs about 5,500 flights a day throughout the world, including those operated by its regional partners. United’s scrapped flights accounted for about a quarter of total the industry’s Sandy-related cancellations.
