I have Qantas Gold status (OW Sapphire), but am currently shifting my alliance to Marco Polo Club. I am only an entry level Green marco polo member at the moment.

I am booked on a trip to San Fran from HKG at Chinese New Year and I expect economy to be very full and would like to maximise my Op-Up chances. Do you think I will have any problems with checking in using my QFF status, and then changing my recorded program to Marco Polo Club when I'm in the lounge at HKG? Anyone else had any experience on this?
