United Airlines says 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.

United, the world's largest airline, said late Wednesday that the storm that came aground in the New York area 10 days ago shaved about $35 million off its profit in October.

But the hurricane-winter storm hybrid boosted its per-passenger revenue by about 1 percent. That's because some stranded travelers were stuffed onto other flights, allowing the airline to improve efficiency.

Delta said last week that Sandy cut its October revenue by $45 million and profit by $20 million.
