2️⃣ Royal Caribbean Group

Royal Caribbean Group is the world’s second-largest cruise company and is known for operating some of the most innovative and technologically advanced ships at sea.

The group owns three major cruise brands outright and also holds a 50% stake in TUI Cruises, the German cruise operator.

Its portfolio includes:

  • Royal Caribbean International – 29 ships, including the revolutionary Icon Class vessels and the newest additions, Star of the Seas and Legend of the Seas.

  • Celebrity Cruises – 17 ships, with Celebrity Xcel joining the fleet in late 2025

  • Silversea Cruises – 13 luxury expedition and ultra-luxury ships

  • 50% ownership of TUI Cruises, which operates the Mein Schiff fleet and Hapag-Lloyd Cruises

It’s worth noting that Marella Cruises is not part of Royal Caribbean Group. Although both TUI Cruises and Marella are linked to TUI, Marella Cruises is wholly owned by TUI Group, while TUI Cruises is a joint venture between TUI Group and Royal Caribbean Group.

Royal Caribbean Group currently operates a combined fleet of around 69 ships, serving destinations worldwide from Alaska and the Caribbean to Antarctica and Asia.

3️⃣ Norwegian Cruise Line Holdings (NCLH)

Completing the industry’s “Big Three” is Norwegian Cruise Line Holdings, which owns three premium cruise brands.

The company operates 34 ships across:

  • Norwegian Cruise Line – 20 ships, with the newest Prima Plus and Prima Class ships expanding the fleet

  • Oceania Cruises – 8 ships, including the recently launched Allura

  • Regent Seven Seas Cruises – 6 ultra-luxury ships

Norwegian Cruise Line Holdings focuses on premium and luxury cruising, offering everything from family-friendly Caribbean sailings to all-inclusive luxury world cruises.

The company also has one of the largest future order books in the industry, with several new vessels planned over the coming decade.

So, What’s the Difference?

While each of these parent companies operates globally, their approach varies:

  • Carnival Corporation The largest and most diversified, with a wide range of offerings from budget-friendly fun to ultra-luxury voyages.

  • Royal Caribbean Group Synonymous with innovation and mega-ship design, with a strong presence in the luxury and expedition sectors.

  • Norwegian Cruise Line Holdings Known for flexibility and informal cruising, with a growing emphasis on ship design and upscale experiences.

The Lowdown

While hundreds of cruise ships sail the world’s oceans, the majority belong to just three parent companies: Carnival Corporation, Royal Caribbean Group and Norwegian Cruise Line Holdings.

Together, these giants account for around 80% of global cruise capacity, owning many of the household names that passengers book every year.

However, some popular cruise lines remain completely independent of the Big Three, including MSC Cruises (sometimes included in “The Big Four”), Virgin Voyages, Disney Cruise Line, Viking, Saga Cruises, Fred. Olsen Cruise Lines and Explora Journeys.

Understanding who owns each cruise line can help travellers better compare loyalty programmes, onboard experiences and the overall style of holiday offered across different brands.
