Although most cruise passengers hail from the United States, it's common for cruise lines to register their ships in foreign countries -- often referred to as "flags of convenience" -- while headquartering themselves in America.
Below, we tell you where several of the most popular cruise lines' ships are flagged and where you can find their headquarters.
A member of the Royal Caribbean Cruises Ltd. family, Azamara's ships are all registered in Malta. The line's headquarters can be found in Miami.
Carnival Cruise Line, a subsidiary of Carnival Corporation & plc, maintains offices in Miami. The majority of its fleet is registered in Panama, with a few vessels flying the flags of the Bahamas and Malta.
Celebrity Cruises is part of the Royal Caribbean Cruises Ltd. family, with headquarters near Royal Caribbean's in Miami. Most of its vessels are registered in Malta, but a couple are flagged to the Bahamas. Its expedition ships are registered in Ecuador.
Part of Genting Hong Kong Ltd., Crystal Cruises has its corporate headquarters in Los Angeles. It has both a river cruising division and an ocean one that operates a mix of Bahamas- and Malta-flagged ships.
Like Disney's other mouse-themed operations, Disney Cruise Line (part of The Walt Disney Company) makes its home in Celebration, Florida -- about 30 minutes from Orlando. All of the line's ships are registered in the Bahamas.
