I know I've seen this somewhere before, but my search skills this morning are drawing a blank.

OK, my status hits 1P soon, and I'm currently waitlisted for an upgrade from an H fare on UA 6 (LAX-JFK) using miles. I talked to MP and asked if having them remove and reenter my MP # when I hit 1P will affect the waitlist.

I know 1P will give me a better shot--too bad I miss 1K for the year, but I couldn't get a SIN trip approved by my company (they require advanced notice of all foreign travel, personal or otherwise) in time to take advantage of MPW124 (oh, well). But my question to MP that I have yet to get an answer for is: will removing and reentering my MP # lose my place on the waitlist, and if so, will it be worth it to get the 1P status reflected?

And should I be going about the upgrade differently (miles vs. SWU vs. 500-milers, etc.)? Just curious--thanks!
