Where cruises from Southampton actually go
Norway is the biggest draw from Southampton, mostly from May to August. Week-long trips to northern Europe and to Spain and Portugal run for much of the year, the Mediterranean usually takes two weeks because the ship has to go round Spain first, and Queen Mary 2 crosses to New York through most of the year. The counts on each card come straight from the schedule.

Norway and the fjords
The largest group on the list, mostly May to August and usually 7 to 14 nights. Stops include Alesund, Haugesund, Stavanger, Bergen, Olden and Skjolden. The longer trips go past the Arctic Circle to Tromso and Honningsvag, or out to Iceland and Greenland.

Northern Europe
The shortest trips from Southampton, and the ones that run all year. Many are MSC's 7-night round trips calling at Le Havre, Zeebrugge, Hamburg and Rotterdam. Cunard and Princess sell longer ones that mix those ports with Belfast, Dublin and Scotland.
155 sailings · 2 to 17 nights · from US$129

Spain, Portugal and the Canaries
Week-long trips down the Atlantic side of Spain to Bilbao, Gijon, La Coruna and Vigo, often as far as Lisbon. The longer ones, 12 nights and up, reach Madeira and Tenerife. They run most of the year, with the most sailings from May to October.
128 sailings · 4 to 28 nights · from US$419

Transatlantic and North America
Mostly Cunard's Queen Mary 2, which crosses to New York in 7 nights with no stops and also sells longer round trips from the same departures. Others take the northern route through Iceland, or go on to Halifax and Boston. Many are one-way, so the journey home is part of the plan.
71 sailings · 7 to 43 nights · from US$399

Mediterranean
Two weeks is the usual length, because the ship has to go round Spain and Portugal first, so expect sea days at each end. Common stops are Barcelona, Malaga, Cartagena, Alicante and Civitavecchia for Rome, often with Lisbon or Seville on the way.
48 sailings · 5 to 40 nights · from US$376

Baltic
April to September, mostly around 14 nights. Stockholm, Tallinn, Helsinki, Visby and Klaipeda are the main calls, with Copenhagen and Warnemunde on the way. Some are one-way and end in Copenhagen or Stockholm, so check the end port before you book.
43 sailings · 11 to 41 nights · from US$2,159

World cruises and long voyages
World cruises and their segments, sold from Southampton by Cunard, Princess, MSC and Regent, plus long voyages to South America, Africa and Asia. These are long, and many end far from Southampton.
43 sailings · 8 to 113 nights · from US$898
