I am E75 and my wife E35 and I am looking to make a flight pass booking for us both for the end of the year. I will be attempting an eUp using my credits and if I have enough, I will attempt an eUp for my wife. If it works out that I will end up instead trying to eUp using my wife's credits, is all that is required is to call in and request a split of the PNR so she can use her credits?
