Cruise to Caribbean from UK - No fly both ways is it possible?

[TheOriginalSweatyBetty]

Has anyone been on a cruise to the Caribbean from the UK without flying there and back? I can’t seem to find any where you sail from the UK and then sail back afterwards. It looks like you can sail out but you have to fly back.
I’m completely new to cruises so apologies if this is a stupid question 🙈

I’ve not heard of a cruise like that. I think you can cruise from Southampton to New York?

Usually the crise ships spend the summer in the Mediterranean and then go to the Caribbean for the winter. So you can cruise over there if you go on one which is heading that way, but it wouldn't be coming back until the end of the season.

It would also take a very long time and be pretty boring as there are no stop offs on the way there or back, and it would cost a lot because you would be on the ship for many weeks - it's usually 7 days for a transatlantic crossing.

Looks like the QM2 does a round trip like this. But it's 26 days and only happens once a year.

Thank you for your replies.
Thanks to @HungryHippo11 I appreciate this.

I don't think they do any. The nearest you could do is one way, then pick up the Queen Mary 2 for the return.

The cruise ships normally have a circular route around either the med or the Caribbean, the only time they go cross Atlantic is what they call 'repositioning cruises' at the start or end of the season.

The Queen Mary is a transatlantic liner so usually does UK to New York.

Have a look.

Several cruise lines do round trips to the Caribbean each year. They normally sail to and from Southampton and the whole trip takes about 4 weeks, with lots of sea days.
Suggest you have a look at P and O and Cunard.

Don't think you can. Would take too long. Flycruise much better.
