British Airways is raising capacity by 10% between London and Barbados this summer.
A new Boeing 787-10 Dreamliner is being deployed on the route from Gatwick for the season while frequency from Heathrow is being increased.
The four-class aircraft features an eight-seat first class cabin, 48 seats in business class, 35 in premium economy and 165 in economy.
BA chief planning and strategy officer Neil Chernoff said: “As British Airways celebrates its 70th year of connecting London and Barbados, we are thrilled to be increasing capacity on the route with a larger aircraft and the launch of a new double daily service from Heathrow.
“This is a testament to the popularity of the route from a leisure and business perspective, and its importance as a link for visiting friends and relatives.
“Our commitment to this special destination remains as strong as ever, and we are proud to offer unparalleled connectivity and convenience for our customers.”
Cheryl Carter, Barbados Tourism Marketing UK director, said: “We are truly honoured that British Airways has chosen to deploy its prestigious Dreamliner 787-10 aircraft to Barbados.
“This shows BA’s confidence in the robust passenger demand for travel between the UK and Barbados.”
A series of events will be organised this month to mark the anniversary of the first BA flight to Barbados in 1954.
