                 CARNIVAL CORPORATION & PLC REVISES 2006 OUTLOOK


      MIAMI (May 16, 2006) -- Carnival  Corporation & plc (NYSE/LSE:  CCL; NYSE:
CUK) announced today that it is revising 2006 earnings guidance based on several
items,  including  lower  revenue  yields,  higher  fuel  costs  and a change in
accounting.

      Earnings  for fiscal 2006 are now  expected to be in the range of $2.65 to
$2.75 per share,  roughly  in line with 2005  earnings  of $2.70 per share.  The
company  expects  earnings for the second  quarter of 2006 to be in the range of
$0.43 to $0.45 per share.


      Details of the revisions to the company's guidance are as follows:

      o     The  company   has  reduced  its  outlook  for  net  revenue   yield
            improvement on a local currency basis ("constant  dollar basis") due
            to further  weakness in  bookings,  principally  for sailings in the
            Caribbean  during the second half of 2006.  Net revenue  yields (net
            revenue  per  available  lower  berth day) for the year in  constant
            dollars are now  expected  to increase 1 to 2% versus the  company's
            previous guidance of an increase of approximately 2 to 3%. This will
            reduce  earnings by  approximately  $0.10 per share.  Because of the
            strengthening  of the euro and sterling  relative to the U.S. dollar
            since the time of its last guidance in March, the company  continues
            to expect  full year 2006 net revenue  yields in current  dollars to
            increase approximately 1 to 2%.

      o     Since the company's  previous  guidance,  fuel costs have  increased
            significantly  and are expected to further impact earnings per share
            for the year 2006 by approximately  $0.07. The cumulative  impact of
            higher  fuel  prices  for  full  year  2006 is  expected  to be $265
            million,  or $0.32  per  share,  compared  to the  prior  year.  The
            company's  guidance is based on the  forward  curve for fuel for the
            remainder of the year of approximately $372 per metric ton.

      o     The  company's  guidance  for the  remainder of the year is based on
            currency  exchange rates of $1.27 to the euro and $1.86 to sterling,
            which benefits  guidance for the year by $0.04 per share compared to
            previous guidance.

      o     Commencing  with the first quarter of 2006,  the company will change
            its accounting  policy for dry-dock costs from  amortizing them over
            the  time  between  dry-docks,  generally  two to  three  years,  to
            expensing  dry-dock  costs as  incurred.  This change in  accounting
            principle   will  reduce  full  year  2006  earnings  per  share  by
            approximately  $0.08,  including  $0.04 per  share in the  company's
            previously released 2006 first quarter, and $0.04 per share over the
            balance of the year.

      With regard to the revised  outlook,  Carnival  Corporation & plc Chairman
and CEO Micky Arison commented "Although we are disappointed having to lower our
guidance for the year, we believe the  fundamentals of our business remain sound
and our long-term  strategies  position us well to grow our business in 2007 and
beyond."
