The Transatlantic Cruise Guide: Routes, Sea Days, and What to Expect
Everything about crossing the Atlantic by ship: routes, duration, what to do on 5+ sea days, repositioning deals, best ships, and honest advice on whether it's right for you.
Quick Answer
A transatlantic cruise takes 6–14 days depending on the route and number of ports. Most crossings have 4–7 consecutive sea days. Queen Mary 2 (Cunard) is purpose-built for ocean crossings. Repositioning sailings in April–May and October–November offer the best value — sometimes 50–70% cheaper per night than comparable Caribbean itineraries. It suits travelers who genuinely enjoy shipboard life; if you're bored without daily port stops, it's not the right trip.
