I remember that DL promotion. It was great because it applied to all of their (then) many ff partners. I got the 100K.
Another (somewhat) great promotion they had a couple of years ago which I haven't heard about since was 40K bonus for all elites / 25k for generals who flew 4 international segments on DL. My Boston --> Montreal trips counted - so, I came out 120K better with no work. I already had 6 round-trips scheduled for the period. A friend of mine at DL said that the promotion was sooverwhemingly popular that they lost stacks of money on it and that it would never be run again.
Oh, the good old days at DL!!
