A standard transatlantic crossing on a dedicated ocean liner like the Queen Mary 2 typically takes 7 nights. In 2026, Cunard maintains a regular schedule for this route, usually departing Southampton around 5:00 PM and arriving at the Brooklyn Cruise Terminal in New York at approximately 6:30 AM seven days later. This "classic" speed is designed for passenger comfort and stability across the North Atlantic. However, some repositioning cruises or itineraries that include stops (such as Le Havre or Halifax) can extend the journey to 9 to 12 nights. Because ocean liners are built with deeper drafts and more powerful engines than standard cruise ships, they can maintain a faster and smoother pace even in rougher seas, making the 7-day crossing the most consistent and popular duration for travelers who prefer the traditional "sea bridge" experience over flying.
