There will also be more departures from Gatwick to New York (JFK).
The Orlando route starts on April 4, 2015 with weekly departures on Saturdays with launch fares of £199.
The airline will increase its number of weekly flights between Gatwick and New York from three to six a week from next May.
Orlando will also be served from Copenhagen.
The airline’s chief commercial officer Thomas Ramdahl said: “We´re happy to announce that we will offer Orlando as a new destination from London and Copenhagen.
“Orlando is already a very popular destination being offered from Oslo and we are looking forward to giving even more passengers the chance to visit this great area of Florida.
”As we are taking delivery of our eighth 787 Dreamliner next spring, we will also have the capacity to add more departures on existing routes that have been very well received.”
