I was recently travelling with

, I just went to the SkyP check-in counter at the airport and the agent processed my upgrade for the exact same price on the spot.
So it never hurts to ask!
There was a post in the most recent couple of pages that an agent was unable to do an upgrade on a Delta ticket, though space was available. Wonder what the difference is? Maybe that was a skyclub and you were at the check-in counter (though one might hope each of those agents would have access to the same actions - maybe not?)
I will ask; I will not hold my breath. I'm one of the few who likes the AF prem econ seat and do not have a problem sleeping in it on a TATL flight.
