Costa cruise line ships range in size from about 820 feet in length to more than 1,000 feet. Typically, larger ships travel popular routes with longer itineraries, though this is not always the case.
In 2014, the company added a new flagship called the Costa Diadema, which measures 1,013 feet long and has a passenger capacity of just under 5,000 people. Costa Cruise is headquartered in the United Kingdom and specializes in European cruises. Its European division is operating a fleet of 12 ships as of 2015. The company also offers cruises in Africa, Asia, South America and the Caribbean with a variety of itineraries and price ranges.
