P&O Cruises’ Iona Celebrates Five Years at Sea

P&O Cruises’ flagship vessel Iona has reached an impressive milestone, marking five years of service since joining the cruise line’s fleet. Since her debut, Iona has become one of the most recognizable and celebrated ships sailing from the UK.

A Record-Breaking Addition to the Fleet

Delivered by renowned German shipbuilder Meyer Werft in October 2020, Iona made history as the largest ship ever built for a British cruise line. She is part of Carnival Corporation’s Excel-class ships and was also the first liquefied natural gas (LNG)-powered cruise ship designed specifically for the UK market, reflecting a major step toward more sustainable cruising.

Designed for Comfort, Entertainment, and Scale

Built to accommodate over 5,000 passengers, Iona offers a wide array of onboard amenities designed to suit every type of traveler. Highlights include:

• Multiple fine-dining and casual dining venues
• Expansive entertainment and performance spaces
• Several swimming pools and infinity pools
• Numerous whirlpool spas and relaxation areas

The ship’s innovative design and modern features have helped redefine the cruise experience for UK travelers.

From Pandemic Pause to UK Favorite

Although Iona was delivered during the global pause in cruising caused by the pandemic, she eventually welcomed passengers once P&O Cruises resumed UK sailings. Her inaugural voyage departed Southampton in August 2021, complete with a celebratory send-off.

Since then, Iona has operated year-round from Southampton, becoming a familiar and popular presence at the port and a cornerstone of P&O Cruises’ UK itineraries.

Five Years Strong—and Counting

Five years on, Iona continues to symbolize innovation, scale, and modern cruising for British travelers. As she sails into her next chapter, the ship remains a standout example of how cruise travel has evolved—combining sustainability, luxury, and unforgettable experiences at sea.
