We got lucky for our Princess cruise in Nov 06. We were able to use our FF miles with United for two round trip business class flights LAX to Rome. It only cost us $91 each. Saving all those miles finally paid off. Good luck in your search. We are booked on a cruise with Princess in July 06 our airfare with Princess was $900 R/T LAX to London each, we upgraded to Business Class for only $2200 more. The listed United fare for Business Class was over $10,000 R/T per person, our Ta could not belive that Princess could offer us such a good fare. Try your cruise line, they may have a good rate.
