It is a shame that someone cannot come to a British Airways frequent flyer forum and ask a question like that - it seems more reasonable and valid for the frequent flyer than continual banging on about what wine is where, meal serving orders or pillow plumpness.
Perhaps she was hoping for some support in providing the fare and card colour information, not offering it as an badge of honour. It almost seems logical to suppose it might give the question more weight, not realising that by mentioning you are a member of the FFP the forum is supposed to support will unleash a bizarre type of anger and suspicion.

Yes, it's an assumption but no more so than the crass assumptions that have been made - relentlessly - further up. In this case it's more worthy of a mention because it's avoiding the series of replies assuming him/her being a Blue/Bronze/Blank on an award booking/cheap ticket and how she should feel lucky to get a seat at all and allowing us to go straight to the "Who Do You Think You Are?" part. The OP could never win here.

These threads rarely become about the OP's question or issues but the paranoid insecurities of some of those that choose to reply.

My assumption is that the guy that moved was not a FTer because no doubt he would have been on here - outraged - by some crazed woman who demanded he be moved from his superior, coveted seat to the dorm down below and full of self-loathing because , for whatever reason, he felt he could not say "No" or even "I need to be here because..." preferring to seethe for hours or days about the treatment.

Maybe he was just a decent guy who feels a Club seat is a Club seat, who did a favour for a passenger and crew and just wanted to get to the other end.
