More than 200 staff have been working on the renovation over the winter. Other improvements to the terminal include additional passenger and baggage x-ray machines and a redesign of the drop-off and pick-up area.

Port operator ABP Southampton said the project was critical to ensure Southampton retains its title as Europe’s leading cruise turnaround Port amidst a predicted rise in passengers.

An increased number of cruise ships visiting Southampton, coupled with the rising capacity of new ships, means P&O Cruises, Cunard and other brands of the Carnival Group, are expecting passenger volume to increase by 25% at Southampton over the next two years.

Carnival UK port service and government affairs director, Steven Young, said: “The Carnival cruise business at Southampton continues to go from strength to strength and with the introduction of new larger ships such as P&O Cruises’ Britannia, it is important that improvement to the cruise terminals and our passenger journey keeps pace.

“With the reopened Mayflower terminal we aim to keep this as free flowing and stressless as possible.

“The improved passenger lounge, together with increased check in and security areas will allow us to ensure just that and give our customers passing through Southampton the very best passenger experience with reduced congestion.”

ABP Southampton director, Nick Ridehalgh, added: “We are incredibly proud to hold the title of Europe’s leading cruise turnaround port but, as always, we will never rest on our laurels. We are committed to investing heavily in our facilities in order to help port-related businesses grow and provide world-class service to their customers.”

The Mayflower Cruise Terminal is one of four in Southampton and handles calls by ships such as Queen Mary 2, Ventura and newly launched Britannia.

Moe than 280 of Southampton’s 440 cruise ship calls to the port are by brands within the Carnival Group.
