I booked a transatlantic in April of 2008. Our original price was $1,600 per person for a balcony cabin on a 15 night cruise. About 45 days prior to the sailing date the price dropped to $749 for a guaranteed balcony. I was able to get that price even though my final payment was already paid. We went through the time change on the way over--next time we'll fly over and cruise back to the US.
