to avoid her getting an email about it, you can change the email on the booking to yours, run the upgrade and then change it back.
Interesting to read that you have actually done it.
I always use the same credit card for booking and upgrades so I assumed that it has to be that way. My bad.
Concerning the e-mail address: I am not sure it is OK to change the e-mail address in a booking without the booked pax knowing about it, although it is certainly possible with name and booking reference to access the booking and change all kinds of things. Would feel somewhat uncomfortable doing that.
