Again, I think the bone of contention centers around actual vs. total miles. I can easily imagine. . .okay, maybe not "easily" but I can imagine how one can accumulate 25M miles what with bonuses, credit cards, and all the rest of it.
However, I still think anyone who has managed to actually fly 25M miles really deserves some kind of award. I just read in Bob Hope's obituary that he claimed to have logged 10M miles in his career which spanned god knows how long and that's total miles not since the advent of frequent flyer programs.
And, FWIW, I don't think raising doubts about anyone's truthfulness in this forum is appropriate. In my mind, you have the choice to believe or not believe without impugning anyone's motives or integrity.
