With oil prices having plummeted to $46 a barrel, Carnival Corp. has suspended (not eliminated) its fuel supplement for all of its major brands: Seabourn, Cunard, Holland America, Princess, Costa and Carnival.

This is how it will work:  A refund of the fuel supplement will be made in the form of a shipboard credit for all bookings within the final payment period for departures on or after December 17, 2008. All bookings outside of the final payment period for departures on or after December 17, 2008 will be adjusted to remove the fuel supplement and guests will be provided with a revised final payment amount.

I am confident the other cruise lines will follow suit shortly. 

Now, if only for the airlines!
