Big fleet news from inside Carnival Corporation: Cunard's youngest liner, Queen Anne, is leaving the brand. After finishing her 2028-29 world cruise, the ship will get an extensive refurbishment, a new name, and join sister line P&O Cruises in May 2029. Carnival UK president Paul Ludlow framed it as a portfolio-wide reshuffle, matching each ship to where guest demand is strongest.

Queen Anne will still have a full send-off as a Cunard ship. She's booked for a central role in the Four Queens celebration in Liverpool in May 2028 — a rare moment when the whole Cunard fleet gathers — and then sails her final world voyage under the Cunard flag from January 2029. If you've ever wanted to sail her in Cunard livery, those are the last chances.

For P&O Cruises, Queen Anne will become a new class of ship entirely. Ludlow described her as a bold, contemporary take on Cunard — hallmark service and sense of occasion paired with modern design, lots of dining and entertainment options, and unusually flexible public spaces. That scale and style will be new to the P&O fleet, and after her reimagining she should sit comfortably alongside the line's more casual British holiday experience.

Cunard, meanwhile, will run a tighter, three-ship fleet centred on Queen Mary 2, Queen Victoria and Queen Elizabeth — the classics most people associate with the brand. The company insists this isn't a retreat: next year Queen Mary 2 gets a major upgrade, keeping the world's only true ocean liner on regular transatlantic service.

There's a second move in the announcement too. Arcadia, a P&O fixture for more than two decades, will run a special farewell season ending 21 August 2029, then transfer to Holland America Line — staying within the Carnival family rather than leaving it.

Why does this matter if you're booking a cruise? First, timing: bookings on Queen Anne's 2028-29 world cruise and her final Cunard season could become collector's items for line enthusiasts. Second, P&O guests get a genuinely new class of ship in 2029, with a style and itinerary range the fleet hasn't offered before. And third, Arcadia fans who dread saying goodbye will find her sailing on under a different (but still familiar) flag at Holland America. Expect refit details and itineraries for both ships to be announced as 2029 approaches.
