World cruise giant hits trouble after accidents

A fire breaks out in the engine room of the Costa Allegra, which is carrying 636 passengers, including eight Americans.

Over its 41 years, Carnival Cruise Line has had a checkered past. In its heyday, Carnival was the cruise brand known for innovation, but more recently it has become known as the brand with PR disasters to deal with.

SYDNEY, Australia — Authorities were conducting an air and marine search Thursday off Australia’s east coast for two cruise passengers who were believed to have fallen overboard the night before. The couple from New South Wales were discovered missing Thursday morning after the Carnival Spirit docked at Sydney’s Circular Quay, at the end of a 10-day journey, said New South Wales state Police Superintendent Mark Hutchings.

Carnival Cruise Lines will spend more than $300 million on a program to update all of its ships with improved emergency generators, engine rooms, and fire systems.
