I was also on this flight and filed a claim today for both me and my companion. We'll see what happens! AF was 1J1Y and the concierge offered me a seat but he really needed to return home so I asked her to give him my seat. He ended up in Y because of no status so at the very least I hope we can get the difference in miles for the segment (we were on AP tickets). He actually only got home 2 hours before me because of a misconnect at YUL and had to overnight there.
