(Reuters) - Spirit Airlines SAVE.N on Friday cut its third-quarter outlook for a key revenue measure as it estimates an approximate $25 million hit on its sales, hurt by hundreds of flights cancellations due to Hurricane Dorian.

The company now expects third quarter unit revenue to fall between 2.5% and 3.5% compared to its prior estimate of a decline of 1% to 2%.

The hurricane has led airline operators including American Airlines AAL.O and Delta Air Lines DAL.N to cancel thousands of flights across the United States this week.

Dorian, which briefly made a landfall on the Outer Banks of North Carolina on Friday, is expected to bring tropical storm winds to Nantucket Island and Martha’s Vineyard, Massachusetts early on Saturday.
