Carnival Cruise Line has withdrawn select Platinum-tier loyalty perks on four long-duration sailings departing from the United States and operating across the Caribbean. The affected itineraries, scheduled for January 2026, include voyages from Miami, Mobile, and Galveston. The decision follows a rise in elite membership levels, which created operational challenges onboard. Diamond-tier guests remain unaffected, while the move is described as a temporary measure ahead of Carnival’s upcoming loyalty programme changes.
