Delta Air Lines, which has hubs at New York’s John F. Kennedy International and LaGuardia airports, said it expects its operations to be back to normal Thursday after the Northeast storm.

Atlanta-based Delta said it canceled 130 flights Wednesday due to the winter storm Juno. That brought the airline’s total storm-related flight cancellations over three days to 1,800 across its system.

Some Delta employees at JFK slept on parked airplanes in business class on Monday night, when public transit was suspended in New York.

Dallas-based Southwest Airlines, the second largest carrier at Hartsfield-Jackson, canceled about 70 flights on Wednesday, nearly 350 on Tuesday and 130 on Monday across its system.
