There are several Perkology-related loopholes that have been discussed at length in various places on FT. But highlighting these loopholes does no one any good in the long run.

Furthermore, I can tell you that NW has a long history of retroactively closing sinilar loopholes long after a promotion has ended and points have been posted. (I for one have the -45k entry in my account history to prove it.)

Given the official NW presence on these boards, this thread should probably be deleted.
