Cunard vs Princess 2026: Carnival Corp Siblings with Different Dress Codes

Cunard and Princess are siblings within Carnival Corporation, both positioned above mainstream lines but at different price and formality levels. Cunard is the luxury brand: 4 Queen class ships, themed Gala Evenings, three-tier dining, and the only scheduled transatlantic crossing on Queen Mary 2. Princess is the premium brand: 17 ships, MedallionClass wearable technology, Alaska dominance, and Star Princess as the first Sphere class ship at 177,882 GT.

For travelers deciding between these two Carnival Corporation lines, the split comes down to formality and travel goals. Cunard is for tradition-first travelers who want the QM2 crossing and Gala Evenings. Princess is for destination-first travelers who want Alaska, MedallionClass tech, and a premium experience without Cunard’s dress code commitment.

What does Cunard do better than Princess?

Cunard wins on formality, heritage, transatlantic service, dining tiers, and world cruises.

• Transatlantic crossings. Queen Mary 2 runs a regular Southampton-to-New York transatlantic schedule. Princess does not offer a scheduled ocean crossing.
• Gala Evenings. Cunard’s themed formal evenings (Black and White, Red and Gold, Masquerade, Roaring 20s) with ballroom dancing are the most elaborate in the industry. Princess’s formal nights are more conventional and start only on 7+ night sailings.
• Three-tier dining. Britannia, Princess Grill, and Queens Grill create distinct dining experiences by cabin grade. Princess offers main dining and specialty restaurants but does not tier the main dining experience by cabin type.
• Heritage. Founded in 1840, Cunard carries 185 years of continuous maritime history. Afternoon tea in the Queens Room, White Star service, and a planetarium on QM2 reflect a tradition that Princess, founded in 1965, does not match.
• World cruises. Cunard sails full 100+ night circumnavigations from Southampton each January. Princess offers extended voyages but not at the same scale or departure consistency.

What does Princess do better than Cunard?

Princess wins on Alaska expertise, fleet size, MedallionClass technology, pricing, and homeport breadth.

• Alaska. Princess is the dominant cruise line for Alaska Inside Passage sailings, with more Seattle departures than any competitor. Star Princess and the broader Princess Alaska fleet offer decades of Alaska-specific shore excursion partnerships and destination programming. Cunard sails Alaska occasionally but not with the same depth.
• MedallionClass technology. The OceanMedallion wearable enables keyless cabin entry, on-demand food delivery, personalized wayfinding, and contactless payments. Cunard does not offer comparable onboard technology.
• Fleet size. Princess operates 17 ships from 6+ US homeports. Cunard operates 4 ships with limited US departures. Princess gives more choice in dates, ports, and ship types.
• Price. Princess’s premium pricing typically runs 25 to 45 percent below Cunard for comparable sailing lengths. The value gap is widest on Caribbean and Alaska itineraries.
• Movies Under the Stars. Princess’s outdoor cinema on most ships is a fleet-wide signature. Cunard does not have an equivalent outdoor entertainment feature.

Where are Cunard and Princess roughly equal?

Both are Carnival Corporation brands with above-mainstream service, dress-up evenings, and Caribbean itineraries.

• Service quality. Both lines deliver attentive service above the mainstream standard. Cunard’s is more formal. Princess’s is more warm and tech-enabled. Both are well-regarded.
• Dress-up evenings. Both maintain dress-up nights, though Cunard’s are significantly more elaborate and more frequent on shorter sailings.
• Caribbean sailings. Both offer Caribbean itineraries, though Princess’s larger fleet provides more options.

Which one should you book?

• Book Cunard if you want a transatlantic crossing on Queen Mary 2, themed Gala Evenings, three-tier dining, or the most formal atmosphere in the industry.
• Book Princess if you want Alaska Inside Passage expertise, MedallionClass wearable tech, a premium experience at moderate pricing, or a wider range of itinerary options from US homeports.
• Book Celebrity instead if you want modern design-forward premium cruising. See our Cunard vs Celebrity and Celebrity vs Princess comparisons.

What to verify before booking

• Current pricing for your specific ship, date, and cabin category on both lines.
• Queen Mary 2 transatlantic schedule if the crossing is your primary goal.
• Princess Alaska departures if Alaska is your priority. Book early as popular dates sell out months in advance.
• Cunard cabin grade to understand your dining tier (Britannia, Princess Grill, or Queens Grill).
• Formal night count for your Princess sailing length. Cruises of 6 nights or fewer have zero formal nights.

Bottom line

Cunard and Princess are both above-mainstream Carnival Corporation brands, but they serve different travelers. Cunard is the formal heritage choice with transatlantic crossings and Gala Evenings. Princess is the destination-focused premium choice with Alaska expertise and MedallionClass technology. If you want tradition and formality, Cunard. If you want destination depth and onboard tech at a more accessible price, Princess.
