Best chances for upgrade J to P USA to EU with miles?
I was just wondering which station would give me the best chances of getting a upgrade by miles from the eastern us to CDG?I am looking to fly somewhere mid march next year, i already tried to look in the fare classes but there never seems any free seat left or does AF only open the seats up close to the date?I would prefer to fly out of NYC but i could change to IAD or YUL if i have more chances there.Thanks in advance!
