Carnival Corporation & plc to Voluntarily Rescind Fuel Supplement for Guests Booked Prior to November 7, 2007
Monday March 31, 6:01 pm ET
MIAMI, March 31 /PRNewswire-FirstCall/ -- Carnival Corporation & plc (NYSE/LSE: CCL; NYSE: CUK) has announced a voluntary refund of the company's fuel supplement for applicable U.S. bookings that were made prior to November 7, 2007, under an agreement with the Florida Attorney General's Office.
The fuel supplement, announced November 7, 2007, was applied to all U.S. bookings for voyages departing on or after February 1, 2008, regardless of when the booking was made, for cruises on the Carnival Corporation & plc brands Carnival Cruise Lines, Costa Cruises, Cunard Line, Holland America Line, Princess Cruises and The Yachts of Seabourn. However, this effective date allowed guests already booked at the time of the announcement the opportunity to cancel and receive a full refund.
The company will now refund the fuel supplement for those guests who were already booked at the time the supplement was announced. Refunds for affected guests will be implemented based on cruise departure date according to the following schedule:
-- For cruises departing on or prior to April 4, 2008, guests will
receive a refund in the same form they used to purchase their cruise.
-- For cruises departing from April 5, 2008 through June 23, 2008, guests
will receive an on-board credit.
-- For cruises departing on or after June 24, 2008, guests' bookings will
be adjusted to remove the supplement.
The fuel supplement remains in effect for all bookings made on or after November 7, 2007. The $5 per person per day fuel supplement applies only to the first and second guests in a stateroom and will not exceed $70 per person per voyage. Also, at the time the fuel supplement was announced, travel agents whose clients had existing reservations were offered $10 per booking in administrative compensation for notifying those clients of the supplement. Those travel agents will still receive the $10 per booking.
