I have a strange situation.

I'm living in the UK and almost Silver BA (Qantas Gold equivalent). I'm also Qantas Gold but it expires this month.

I'm flying Qantas tomorrow night and I have put in for an upgrade return to Business. I'm waiting to find out if I'm going to be successful.

Now I have used by Qantas Gold to increase my upgrade chances in the system, but if I don't get the upgrade, Qantas Status is useless to me and I might as well credit it to BA. I do however want to maintain my return leg as Qantas Gold in case I get an upgrade on the return leg.

Is this possible? Is it also risky to change it for one way as this may impact my upgrade ranking?

Any help would be greatly appreciated.
