There have been some very generous promos. that I'm sure will never be repeated. It was fun while it lasted The best one was last year when KLM matched all teh miles I had in another FF acct. That added a nice high 7 figures to my totals. Cost me around $1500 but could have done it cheaper if I had been really clever. The Million miles on LatinPass was also another winner in my book. Oh, and back in the 80's the 75,000 all inclusive award for FC to Hawaii, suite at the Westin, and rental car came in mighty handy for Spring Break when I was in college.
