Two months ago I was bumped from CX F to J (AA Award) when CX removed the F cabin from the flight. As other FT members suggested, I tried to ask for a liaison repeatedly to get onto another flight in F. But up to now neither a liaison nor the AA twitter team were able to move be to another flight's F, all saying they cannot do anything about my involuntary downgrade unless award space opens up.
Oh, and CX's twitter team didn't respond to my DM. What should I try next?
