Airlines add new flights and routes to Key West, including JetBlue and Allegiant.

Beginning Feb. 23, JetBlue will extend its recently launched nonstop service from New York City and Boston to Key West from seasonal to year-round.

Service from New York’s John F. Kennedy International Airport (JFK) to Key West International Airport (EYW) is scheduled Thursdays, Fridays, Sundays and Mondays, with flights arriving in Key West at 1:22 p.m. and departing for JFK at 2:10 p.m.

From Boston Logan International Airport (BOS), service is also scheduled for Thursdays, Fridays, Sundays and Mondays, with flights arriving in Key West at 12:14 p.m. and departing to BOS at 1:02 p.m.

“Our strong demand as a year-round subtropical island destination is a response to our scenic wide-open spaces, casual island atmosphere and an abundance of water activities,” said Stacey Mitchell, director of the Florida Keys tourism council, in a press statement.

“Visitors from the Northeast, which remains a top visitor market for all of the Keys, are seeking warm breezes, abundant sunshine and organically socially distant experiences such as backcountry excursions, deep-sea fishing charters, legendary sunset celebrations and quality time outdoors with family and friends,” added Mitchell.

JetBlue launched seasonal service to Key West Feb. 11 with the Embraer 190 aircraft with 100 passenger seats, including 16 “even more space” seats and featuring two-by-two seating with leg room. The flights include complimentary, unlimited name-brand snacks and soft drinks, live programing on personal seatback televisions and free high-speed wireless internet.

“Florida has always played a key role in JetBlue’s success story and that continues today as we expand our seasonal Key West flying to year-round service,” said Andrea Lusso, JetBlue’s vice president of network planning, in a press statement.

In addition, beginning June 3, Allegiant is adding nonstop service from Pittsburgh International Airport (PIT) to Key West International Airport (EYW).

Allegiant plans to serve the Key West market with twice-weekly flights scheduled Thursdays and Sundays on Airbus A319 aircraft.

“We’re thrilled to announce another destination with Allegiant as we continue to expand air service options into the beautiful island of Key West,” said Richard Strickland, director of airports for the Florida Keys’ Monroe County, in a press statement.

And, starting June 9 Allegiant is also adding nonstop service from Cincinnati/Northern Kentucky International Airport (CVG) and on June 2 nonstop service from Nashville International Airport (BNA) to Key West. Allegiant’s twice-weekly Key West service, Wednesdays and Saturdays, on both routes is to employ Airbus A319 aircraft.

“Key West offers so many outdoor recreation activities for Pittsburgh residents to enjoy,” said Drew Wells, Allegiant’s senior vice president of revenue, in a press statement. “And Floridians who are looking for a change of scenery will find some incredible attractions in Pittsburgh.”
