Onboard spending money of between $65 and $620 per person is being offered by Cunard to encourage early bookings.
The promotion runs for a week from tomorrow (Saturday) and covers selected 2015 departures, including the line’s 175th anniversary event when all three ships will be in Liverpool for the first time on May 25.
Cunard marketing director Angus Struthers said: “We want our passengers to experience and enjoy all that Cunard has to offer, and we’re launching this festive initiative so that they can relax and indulge themselves on board to the full.
“The only challenge will be how to make the most of the offer benefits.”
