The move will come into effect on 1 April and will apply to all bookings departing from 1 May. The line confirmed agent commissions will typically increase by 1.5% to 2% as a result of the move.
Gary Anslow, vice-president and head of UK and Ireland, said: "This change signifies our commitment to agents, making the commission payments higher, as well as a seamless and transparent booking process.”
It follows a 2% commission hike during wave season, announced in December, and applied to bookings made between 1 January to 31 March.
