Royal Caribbean Cruises Ltd. expects suspended port calls in Mexico amid the outbreak of the H1N1 flu virus to cut 2009 earnings by about 22 cents a share.

Numerous cruise ships temporarily diverted from the country as the illness broke out. The virus "had a short, but highly disruptive impact to our operations," said Chairman and Chief Executive Richard Fain on Tuesday. He added, "Fortunately, our vessels are quickly returning to their original itineraries."

Royal Carribean in April had projected reduced 2009 earnings of $1.35 a share, higher than analysts' views at the time.
