If you have searched “Why are P&O shutting down?”, you may have come across confusing information about P&O Cruises closing. The key point is that the situation involves P&O Cruises Australia, not the UK-based P&O Cruises brand.
P&O Cruises Australia was discontinued as a separate cruise brand in 2025, with its operations being absorbed into Carnival Cruise Line. Carnival Corporation announced this change in June 2024 as part of a strategy to simplify its brand portfolio and improve operational efficiency.
Meanwhile, P&O Cruises in the UK continues to operate. Its current company information identifies Carnival UK Ltd. as the company trading as P&O Cruises, and its website continues to provide booking, cancellation and customer-service information.
This distinction is important for anyone trying to manage an existing booking or access their myp&ocruise account.
No, not as a whole.
There are two different P&O cruise operations that are often confused:
P&O Cruises Australia — the brand was retired in 2025.
P&O Cruises UK — continues to operate under Carnival UK.
The Australian brand's closure was announced by Carnival Corporation in 2024. The company planned to move the Australian operation into Carnival Cruise Line rather than simply stop offering cruises in the region.
Therefore, saying that “P&O Cruises is shutting down” without specifying the region can be misleading.
Carnival Corporation said that the South Pacific market had a relatively small population compared with some of the other cruise markets where its brands operate.
A smaller potential customer base can make it harder for a dedicated cruise brand to achieve the same scale as a larger international operation.
The company therefore decided that combining the Australian P&O operation with Carnival Cruise Line would provide a more efficient structure.
Another major reason was the cost of operating in the region.
Carnival specifically cited significantly higher operating and regulatory costs when explaining its decision to retire the P&O Cruises Australia brand.
Cruise operations involve expenses such as:
Port charges
Regulatory requirements
Ship operations
Crew
Fuel
Maintenance
Administration
Marketing and distribution
When these costs are high, operating multiple separate brands in the same region may not provide the desired economies of scale.
The decision was also part of a broader portfolio strategy.
Instead of maintaining P&O Cruises Australia as a separate brand, Carnival Corporation moved the operation under Carnival Cruise Line. The company described the change as a way to increase capacity and create operational efficiencies.
This means the change was primarily a brand and business restructuring, rather than Carnival abandoning Australian cruising altogether.
The ships did not all simply disappear from service.
Two ships associated with P&O Cruises Australia, Pacific Encounter and Pacific Adventure, moved into the Carnival Cruise Line operation. Pacific Explorer, however, was scheduled to leave the fleet.
This is an important difference between a cruise brand being discontinued and cruise ships being completely removed from the market.
The P&O Australia name disappeared, while some of the ships and cruise capacity continued under Carnival Cruise Line.
Carnival Cruise Line is one of Carnival Corporation's major brands and already has a substantial international operation.
Bringing P&O Cruises Australia's ships and operations into Carnival Cruise Line allowed Carnival to consolidate its presence rather than maintain two separate brands serving the same broad region.
The company's 2024 announcement described the move as part of its strategy to increase Carnival Cruise Line capacity and optimize its overall brand portfolio.
For most UK P&O Cruises customers, the Australian brand change does not mean that P&O Cruises UK has shut down.
P&O Cruises continues to operate as Carnival UK Ltd., trading as P&O Cruises. Its official company information lists its registered office in Southampton.
The company also continues to maintain active booking terms and customer-support services. Its current booking conditions include provisions covering bookings, cancellations and changes to holidays.
So if you have a UK P&O booking, you should not assume that your cruise has been cancelled simply because you read about P&O's Australian brand closure.
If you already have a P&O Cruises UK booking, the brand changes in Australia do not automatically cancel your holiday.
Your booking should be managed according to the terms applying to your reservation.
P&O Cruises currently provides customer support for booking-related questions, including cancellation and transfer queries.
Your booking confirmation should tell you:
Your cruise line
Ship name
Sailing date
Booking reference
Departure port
Passenger information
Payment details
These details can help establish whether your reservation is with P&O Cruises UK or relates to the former P&O Cruises Australia operation.
If you previously used myp&ocruise, check the account associated with your booking.
Keep your booking reference and passenger details available if you need to contact customer service.
If you are unsure about the status of an existing reservation, contact P&O Cruises or your travel agent rather than relying on social-media posts or outdated information.
P&O's current help information provides customer-contact options for booking questions.
Carnival Corporation announced that P&O Cruises Australia would be retired in March 2025.
The company's Australian cruise operations were integrated into Carnival Cruise Line, with the change designed to create efficiencies and increase Carnival Cruise Line capacity.
This explains why some older P&O Australia webpages, references and booking information may no longer work in the same way.
For customers who remember Pacific Adventure, Pacific Encounter and Pacific Explorer as P&O ships, the transition can therefore look like P&O has disappeared completely. In reality, the business was reorganized.
Yes.
As of 2026, P&O Cruises UK continues to operate. Its current website contains active customer-support information, booking terms and cancellation guidance.
There have also been organizational changes within Carnival UK in 2026, including changes involving the leadership structure of P&O Cruises and Cunard. Those changes are separate from the 2025 retirement of P&O Cruises Australia.

Customer accountsAustralian operations transitionedExisting UK customers continue using P&O services
The biggest takeaway is that P&O Cruises Australia and P&O Cruises UK should not be treated as the same business operation simply because they share the P&O name.
There is no factual basis for saying that P&O Cruises UK is currently shutting down.
Its current company information, customer-support pages and booking terms show an operating cruise business.
Cruise companies can change ships, itineraries, leadership structures and business strategies over time. However, those changes should not automatically be interpreted as a complete brand closure.
For customers, the most reliable approach is to check the status of their specific booking rather than relying on a general headline about P&O.
The answer to “Why are P&O shutting down?” depends on which P&O brand you mean.
P&O Cruises Australia was retired as a standalone brand in 2025 and its operations were integrated into Carnival Cruise Line. Carnival cited the relatively small South Pacific population, higher operating and regulatory costs, and the opportunity to improve efficiency as key reasons for the decision.
P&O Cruises UK has not shut down. It continues to operate under Carnival UK, with active bookings, customer support and cruise services in 2026.
For anyone checking a booking through myp&ocruise, the most important step is to identify whether the reservation belongs to P&O Cruises UK or was connected with the former P&O Cruises Australia operation. That distinction explains most of the confusion surrounding the phrase “P&O shutting down.”
