As has been said - gotta love FT!
I had been wondering how I could access an AAA discount (being an auto club member in Queensland, Australia), but I came across this thread, read the discussion, looked at the back of my member card and sure enough sure that tiny "show your card and save" logo!
It's only been about 15 years that I have been a member, and never really had call to look at the back of the card in such a way......

Hats off to Flyertalk... yet again!
