As always, I wonder about the multiplier effect of something like this (see also mile inflation threads). BA isn't going to be in the business of Concording people who buy subscriptions, that isn't viable for them. If EBay reaches an audience that reacts to this that is an order of magnitude greater than FT it could spell real trouble.

FT is great if everyone doesn't know about it. That's the conundrum of information on how to 'beat the system' or take advantage of loopholes. Everyone can't be doing it, it only works if something on the order of quite a bit less than everyone does it. After all most seats are coach and for the airline to survive, most seats must be paid for.
