The US-based airline will operate a daily non-stop service to Santo Domingo in the Dominican Republic and Cancun in Mexico from May 2009, subject to approval from the US government operating authority.
Commenting on the proposed new routes, Marty St George, vice president of planning at JetBlue, said: "We invite you to experience our low fares and lots of frills on our newest service between Fort Lauderdale and the Caribbean."
JetBlue will commence a new twice-daily service to San Juan in Puerto Rico on December 18th, while a further new route to Nassau in the Bahamas will begin on February 1st next year.
Aside from its Caribbean services, JetBlue flies to 13 cities in the US with up to 46 daily departures.
The airline recently won three awards from this year’s Zagat Airline Survey, including ‘Best Large Domestic Airline’ for economy-class seating.
