While you could upgrade anyone you want online , there used to be a higher requirement for upgrading someone else at the airport .
I think one of our members here (I think it was mrtdxb) was told that he could only upgrade someone else at the airport if you were also travelling on the same flight.
Not sure if the rules are still the same as this was around 2 years ago.
I will try to search for that thread and post.
