Savvy cruisers who yearn for days at sea, as well as great deals, look forward to spring and autumn more than any other time of year. This is when repositioning cruises feature as an unsung element of cruise lines' rosters.

Though some ships spend the entire year sailing the same itineraries, many relocate to follow the sun. Few ships stay in Europe when the weather turns, so between September and November there is a veritable armada of ships crossing from Britain and the Med to the U.S. and Caribbean, calling at Iceland and the Canadian Maritimes en route. Likewise, in spring many ships, having spent winter in the Caribbean and South America, head back to the British Isles, Italy, Spain, France and Greece via the Azores, Canary Islands and Iberian Peninsula.

These one-way voyages are often sold at discount prices as they are not part of regular sailing schedules. To attract passengers, cruise lines may theme them with topics ranging from food and wine, to theatre, and big band music. Enhanced enrichment programs also make these voyages appealing.

Here are a few of the repositioning cruises to book in 2025.
