Flights to Barbados direct from the UK take around eight or nine hours. Not as fast as when Concorde used to jet across the Atlantic to the Caribbean but Barbados is still a popular playground for the rich and famous. British Airways is a stalwart for Barbados flights offering up to ten flights a week from Heathrow in the winter. There is also regular, direct Virgin Atlantic flights to Barbados from Manchester and Gatwick.
The best advice we can offer when looking for cheap flights to Barbados is to book early and travel outside of peak travel dates such as Christmas, New Year plus the February and Easter school holidays.
