Few months ago I was at HKG lounge and while checking emails realized that I needed some miles to re-qualify for BA Gold. I did not realize I was op-upped (J->F) until I went to change the FFP from CX to BA. It did not change op-up status but I am unsure whether it was less than 45 minutes before boarding or there was bit more time.
