What a busy few days! First Disney Cruise Line announced they were suspending their fuel supplement, then Carnival Corporation and its six brands (Carnival Cruise Lines, Cunard, Princess Cruises, Holland America Line, Costa Cruises, and Seabourn) announced they were getting rid of their fuel surcharge and late Thursday night Norwegian Cruise Line followed suit.

Well Friday afternoon, Royal Caribbean Cruises Ltd. announced they are suspending their fuel supplement as oil prices hit a four-year low of $40.25 a barrel on Friday. The new policy applies worldwide to sailings that depart on or after January 1, 2009 for Royal Caribbean International, Celebrity Cruises and Azamara Cruises.

Royal Caribbean passengers with existing bookings paid in full for sailings that depart on or after January 1 will receive a refund in the form of an onboard credit. The supplement will be automatically removed for customers with existing bookings who have not paid in full.

Royal Caribbean said it may reinstitute the fuel fee if the price of West Texas Intermediate fuel exceeds $65 per barrel on designated quarterly dates.
