Had to take a flight from Houston to phoenix a couple weeks ago for work, booked IAH-DEN-PHX, PHX-IAH (I needed 3 segments to renew platinum). Being my last trip of the year and only having 20 PP left I thought why not at least try, Put in my plus points request for IAH-DEN knowing it's was highly unlikely but might as well try. Moved me from 74th to 8th with 7 FC open. Oh well I tried. Morning of the flight (took an evening flight) I looked at my flights and PHX-IAH still had 3 seats in FC and i was already 5th just with status so I thought, ok I'll cancel the DEN request and grab the other one since I was still at 8th with only 2 seats left. When I canceled and went back into to request, I got offered and automatic instant upgrade on the IAH-DEN flight instead of a waitlist. I was a little shocked. Nice little treat to end the year.
That said, 36 flights this year, used both my PP upgrades, and got a status upgrade on 23 flights, so 25/36. Not bad.
