British Airways said on Thursday it would raise its fuel surcharge on long-haul and short-haul airfares because of high oil prices, which increase the cost of jet fuel.

"British Airways will increase its fuel surcharge on all tickets issued from Tuesday June 3, 2008. The decision reflects continuing high oil prices," the company said in a statement.

It comes just one month after BA's previous round of fuel surcharge increases. BA said the surcharge for single-fare long-haul flights of less than nine hours would rise by £15 per flight to £78. This means the cost would increase to £156 for return flights.

The surcharge for single-fare long-haul flights of more than nine hours would increase by £30 to £109 per flight. It would jump to £218 for a return fare.

BA added that its short-haul fuel surcharges would be lifted by £3 to £16 per flight, or £32 for a return trip. The announcement came as Southampton Airport owner BAA announced £51m losses on tighter security measures and money spent on the troubled launch of Heathrow's Terminal 5.
