Carnival reports H1N1 virus impact

Carnival Corporation & plc Reports Financial Impact of
Itinerary Changes Responding to H1N1 Influenza Mexico Travel Advisory; Plans
                    Rapid Return to Popular Mexican Ports

    MIAMI, May 18 -- Carnival Corporation & plc (NYSE/LSE: CCL; NYSE CUK)
today announced a financial impact estimated at approximately $0.05 per
share, the majority of which will be incurred in the second fiscal quarter of
2009, as a result of modifications to cruise itineraries for the six-week
period ended June 15, in response to the U.S. Centers for Disease Control
(CDC) recommendation against non-essential travel to Mexico.

    The CDC lifted its recommendation against non-essential travel on May 15,
allowing for ships to return to popular ports in Mexico's coastal resort
areas. However, the potential remains for additional financial impact beyond
June 15 which could range up to approximately $0.05 per share bringing the
estimated total impact to $0.10 per share on full year 2009 results. The
company will continue to monitor booking trends and provide updated guidance
on its second quarter earnings call.

    Three of the company's brands modified itineraries for 27 cruise ships -
16 for Carnival Cruise Lines, six for Princess Cruises and five for Holland
America Line -- to avoid previously scheduled calls in Mexico. In many
instances the modifications involved simply substituting another port while
others required the development of entirely new itineraries. Princess' and
Holland America's Mexico calls are seasonal and conclude this month while
Carnival's are year-round.

    "Our vessels are resuming their original itineraries as soon as practical
but will all be back by the middle of June. The Mexican coastal resort areas
where our ships call are some of the most popular destinations for North
Americans vacationers. We know that our guests are looking forward to
visiting Mexico and that they will have a safe and enjoyable experience
there," said Micky Arison, chairman and CEO for Carnival Corporation & plc.

    Only the Carnival Cruise Lines brand vessels will be impacted by the
change in the CDC advisory. Gerry Cahill, president and CEO of that operating
unit said, "Mexico has so many wonderful sites and attractions and feedback
from our customers suggests that the majority support a resumption of port
calls in Mexico. We know that they and our port destination partners are very
much looking forward to our return."

Lines' vessel will resume its original itinerary is available at
