Carnival Corp. & PLC, the world’s largest cruise operator, said on Monday it expects second-quarter and 2009 earnings to be impacted by swine flu.

The Miami based company said that as a result of cancellation of Mexico stops for three of its cruise lines, it was expecting its earnings to go down by 5 percent. It also said that 2009 earnings could be as much as 10 cents a share off from estimates.

Previous month the company had cut down its second-quarter earnings stance by a penny to a range of 29 cents and 31 cents. It also cut its 2009 earnings estimates by 6 cents to a range of $2.04 to $2.24.

After the U.S. Centers for Disease Control urged travelers to postpone all nonessential travel to Mexico, last month, Carnival had canceled two stopovers in Cozumel and one in Ensenada citing a number of cases of the H1N1 flu virus, widely known as swine flu.

The cruise line will be following the modified itineraries for some of its cruise ships until June 15. These measures have affected 27 ships operating under the Carnival Cruise Lines, Princess Cruises and Holland America Line brands.
