Ever read a cruise deal or forum post and thought, “Am I supposed to know what that means?”
Cruise abbreviations are everywhere. On booking sites. In Facebook groups. Even on ship signage. And if you don’t already know them, they can make perfectly good information feel confusing, frustrating, or totally useless.
They’re meant to save space and simplify things. But when no one explains them, they do the opposite.

So I’ve pulled together the cruise abbreviations you’ll see most often – including a few that catch people out, even after multiple cruises.
Because there’s one abbreviation in particular that almost everyone misunderstands… and it can actually affect what you book.
1. ABTA
Association of British Travel Agents. A UK-based travel association that helps ensure quality and reliable services from its members, including cruise lines.

2. AFT
This isn’t actually an abbreviation – it’s a nautical term. Some people think it’s an abbreviation, though. It refers to the back of the ship. Staterooms labelled as “aft” are located near the rear of the ship.

3. ATOL
Air Travel Organisers’ Licensing. A UK financial protection scheme that covers most air package holidays sold by travel businesses based in the UK.
If your cruise has flights included in the package, you want it to be ATOL-protected. Then you’re guaranteed to be looked after if the airline goes out of business while you’re on your cruise.

4. B2B
Back to Back. Refers to booking consecutive cruises, where a passenger remains on the ship for the next voyage.
5. BPG
Best Price Guarantee. A policy offered by some cruise lines ensures that if a lower price is found for the same cruise, they will match it.
Not all cruise lines advertise this using the abbreviation BPG, but you’ll often see it used by cruisers and agents.

6. C&A
Crown and Anchor. Royal Caribbean’s loyalty program offers rewards and benefits to frequent cruisers.

7. C&S

10. CCL
Carnival Cruise Line. This popular cruise line is known for its fun atmosphere and wide range of destinations. Because it’s typically shortened to just “Carnival”, people sometimes don’t realise that CCL means the cruise line.
11. CO
Cabin Occupancy. Refers to the number of people staying in a cruise ship cabin.
12. DBP
Deluxe Beverage Package. A beverage package offered by some cruise lines that includes a variety of drinks, usually this is the top drinks package. Sometimes called a Premium Beverage Package, though PBP is less commonly used.

13. DCL
Disney Cruise Line. A cruise line that offers family-friendly cruises with Disney-themed entertainment – and yes, they’re pricey – but they’re also excellent.
14. FCC
Future Cruise Credit. Think of it as money to spend on a cruise – usually awarded when a cruise is cancelled or adjusted, in lieu of a refund, so you can use the FCC towards another cruise instead.

15. FOD
Friends of Dorothy. A term used to refer to LGBTQ+ gatherings or meetups on cruises.
16. FTTF
Faster to the Fun. A program offered by Carnival Cruise Line that provides expedited boarding, priority luggage delivery, and other benefits.

18. GTY
Guaranteed Stateroom. A type of booking where the guest is guaranteed a room in a specified category, but the exact room is assigned at a later time.
Where the Y comes from, I actually don’t know. Some people think it comes from “Guaranty” or that it’s a shortened form of “GuaranTee categorY”.
19. HAL
Holland America Line. This premium cruise line is known for its elegant ships and exotic destinations.
