British Airways will launch new flights to Punta Cana in the Dominican Republic and Montego Bay in Jamaica this winter.
The launch of the new routes from London Gatwick means that BA now offers more seats to the Caribbean from the UK than any other airline.
BA is also intending to launch additional flights to St Kitts, Grenada, Barbados and Bermuda next summer, which could lead to an increase in demand for flights to Caribbean destinations from British airports.
London Gatwick Airport’s commercial director Mike Luddy said that he was "delighted" that BA is bringing the "prestigious" routes to the UK’s second-busiest airport.
"BA is a hugely important customer for us and we hope that the addition of the new routes will further strengthen their network and performance from the airport," he commented.
By next summer, BA will operate a total of 55 weekly flights to the Caribbean from London, with 11 destinations served from Gatwick and three from Heathrow.
The airline recently announced that its flights to Hong Kong next summer will be renumbered BA27 and BA28 instead of the existing BA31 and BA32.
