Disco,
I read just the last link you provided. His Delta "flight from hell in first class" was nothing about the flights.
1. He was mad because he bought a first class ticket but his son and relatives bought coach and the agent wouldn't check in the coach people in the first class line with him, thereby bypassing the other coach pax in line.
2. His bag was mishandled during the connection in JFK and arrived in Manchester England a day later.
3. On the way home he was in an RJ (delayed) and it didn't feel like first class anymore.

That was his flight from hell, I kid you not.

Didn't bother to read anymore links.
