This is a very valid point. Periodically questions arise on the AA forum along the lines of "if it's not OK to barter/trade things according to the airline T&Cs, how come we have CC?" The usual answer is something like "because we do."

I haven't read CC in a while, so I haven't seen the attitude change that others have reported, but I have no reason to doubt this. I've used CC in the past and, personally, have no qualms about the trade I've made, despite the fact that some might be seen to violate the T&Cs. These were honorable and fair transactions and, truth be told, I don't care all that much about T&Cs within reason.

FT, as a whole,may not have that latitude and luxury, though.

Cheers.
