Cruise Middle East turmoil not a huge business threat, says Carnival Corp. By Tom Stieghorst / September 25, 2012 Share 1 -- Carnival Corp. said that it has limited exposure to unrest in Middle East and North Africa countries. Beth Roberts, Carnival Corp.'s vice president of investor relations, said during Tuesday's third-quarter earnings call that less than 10% of cruise capacity across all brands would be in the eastern Mediterranean in 2013. She said all Med deployments make up about 6% of Carnival itineraries in the first quarter, 17% in the second, 25% in the third and 28% in the fourth. The average for the year is 19%, and Mediterranean capacity is split about equally between eastern and western routes, she said. Carnival Chairman Micky Arison said Costa Cruises has a small ship in the Red Sea part of the year. "That could be an issue if this continues much longer," he said.
