JetBlue, which operates approximately 20% of its flights in and out of the Caribbean on a typical day, expects to reduce capacity fleetwide by approximately 2.9% below earlier plans because of hurricanes Irma and Maria.

The hurricanes will cost JetBlue $114-$134 million in 2017, the carrier said in an operational update Wednesday.

Among the hard-hit Caribbean destinations that JetBlue serves are St. Croix, St. Thomas and St. Maarten. JetBlue also has the largest operation of any airline in San Juan and serves the Puerto Rican cities of Ponce and Aguadilla.

JetBlue said that Irma and Maria combined to reduce available seat miles by 2.7% in the third quarter while impacting revenue by $44 million.

On a bright note, JetBlue said the demand for Florida should return to normal by the middle of the October to December.

Meanwhile, Allegiant reported Wednesday that Irma's push through Florida forced the carrier to cancel 8% of scheduled September departures. The total number of passengers carried by Allegiant in September was down 10.3% from a year earlier.
