I was booked in bulk V, but as qasr pointed out, it doesn't matter a whole lot. Officially my ticket was nonendorsable, which is why rebooking on NW was so difficult.

FlyUAyounger: I guess the key is being on the ball enough to sub in a different *A FFP when reaccomodated. I've been switched to other *A carriers twice and both times my new BPs already had my MP# printed on them.... so I ended up receiving partner miles only to have them taken away after my UA flights posted. I won't make the same mistake a 3rd time.
