To upgrade a long haul award ticket with a GPU, do the miles used to book the flight need to come from a GS account or can I book award tickets from my 1K account and then have a GS apply a GPU to upgrade?


My family will be accompanying me on a business trip and traveling on the same flights but on a separate PNR. I'll have a paid J seat and I was going to book economy tickets and apply GPUs for my wife, young daughter and lap infant. Unfortunately I waited on pulling the trigger and the flight went from R9 to R0 in the past few days on the outbound so now I'm stuck playing the upgrade lotto.

If I waitlist the GPUs would they clear one at a time if they released one R seat or would/could they be bypassed since I have 2 tickets waitlisted and one is for a 3 yr old and the other has a lap infant attached?
