Caribbean Airlines, CAL, says it will be ending its three weekly flights to London early next year, because they are not profitable.
The London service was launched in 2012.
Last year the airline racked up USD$60-million in losses.
It says the move to drop the London routes will reduce operational costs and allow it to compete harder for the budget-wise leisure travellers on its North American routes.
Since 2013, CAL has been faced with increased competition from low-budget airlines such as Jet Blue and increased flights by US mainline airlines.
The Jamaican government holds a 16-percent stake in CAL.
