Flying SFO-IAD-ZRH-BOM with the ZRH-BOM leg on Swiss Air with my wife in December and the back on all UA metal BOM-EWR-SFO in January. Q class on the way there and W on the way back. A few newbie questions:

1. I don't have any GPUs but have some RPUs - if I apply the RPUs now on the domestic legs can I pull the RPUs if I convince a friend with GPUs left over to trade, etc or is it a done deal once I apply the RPU?

2. Does the fact that I am flying on Swiss Air for the last leg impact my GPU clearing chances? (I know I won't get upgrade on the ZRH-BOM leg)

3. My wife is non-elite and we are on separate PNRs. Will she clear on an RPU/GPU based on my account status or her own if they are coming from my account?

Thanks in advance!
