Andrewcx, this is absolutely excellent ! Yes, it should be a sticky indeed... What can I say ?
I guess we need you to also do a summary for status match. 
Well, whoever does them... another sticky I would really appreciate is on mileage expiry. I have so many smaller (but significant) quantities of miles in so many things (AZ, MS, ET, SQ, LA...) that I can't be bothered to check their expiry and sometimes get bad surprises.
Just one question: I assume that
once you reach Lifetime Plat with AA, then any year when you qualify for Plat Exec, you go up to Plat Exec for the relevant year, and then down to Plat again for the rest, right ?
Cheers, and thanks again !
