Delta Air Lines says Superstorm Sandy cut its revenue by $45 million last month as it was forced to cancel more than 3,500 flights.
The Atlanta company, the world's second-largest airline after United, said its October profit was reduced by about $20 million.
Delta Air Lines Inc. said that it was operating a near-full schedule at New York's JFK and Newark Liberty in New Jersey. But on Thursday it ran at only 80 percent at LaGuardia, which sustained the heaviest flooding and damage. It expects to run a full LaGuardia schedule Friday.
Superstorm Sandy hit the New York area Monday night. As of Thursday, airlines had canceled more than 20,000 flights because of the storm.
Delta expects the storm will have less of an impact on its operations this month.
