Hello, few weeks ago, a friend of mine used to have some miles expiring and he had no plans to travel.
Therefore he asked me if I wanted to use them and he issued on my name an award tix in business class for a two sectors oneway tix..

Then I had to change the date and I was perfectly able to do that.
I noticed that systems offers the chance to upgrade with 40% discount to F class (actually one sector has availability and it seems you can upgrade just on e leg) but he has no more miles in his account.

First question is: is then possible to upgrade an award tix with miles?
Second question: may I use my account (where I have miles) to upgrade? Or is there a way I can transfer some points (i.e. AMEX MR) to his account?

Thanks in advance.
