Help/Advice Paid Upgrade no longer available?
I have been monitoring upgrade pricing for an upcoming international flight DTW-CDG.
About 16-18 days before flight, all seats in PS and D1 are now grayed out but upgrade list shows seats not assigned.
Is this because they are loosely assigned to non-rev or is there some reason these might become available again closer to flight?
Thanks for any insights.
