Airlines are to be charged more for using air traffic control services.
Following months of consultation the control tower operator, Airways, is going ahead with a 7.5% increase in fees, after holding back on putting up prices during the global financial downturn.
From 1 July the fees will go up by between 50c and 90c per passenger per flight.
Carriers will have to decide whether to absorb the extra cost or pass it on to passengers.
A spokesperson for Airways, David Rollo, says that despite the higher charges, the state-owned enterprise will slip into the red for two years.
