I just want to post a thank you to all the people who patiently respond to questions in this thread. When I first joined FT, I was afraid to ask anything, because some FTers seemed to enjoy flaming anyone who asked a question that had already been answered somewhere in the thousands of posts that were already in the AA forum. After several years of being a member, I still can't interpret some of the lingo in the posts by long time members in other threads. I think this thread, and the ones like it for other airlines, represent the true spirit of the FT community and the people who make this thread the friendly, valuable resource that it is deserve a lot of kudos and good karma. Thank you to all of you.
