I have been a member since May 1981 too and have been TOP before Platinum then EXP when they started that. I'm curious about CK, but I've never been offered anything like that, maybe because I do my best to keep their yield down, but still requalify for EXP every year. I did have Swissair Travel Club in 1970's when they met me at ever plane, carried and placed my onboard baggage for me, then brought me to the gate at the last minute. They also cleared all flights everywhere and were great support in then-difficult places like PEK (remember 1978, that one). If CK is anything like the old Swissair Travel Club I'd pay for it happily and begin flying more with AA, which would bring me to about 250,000 or so flight miles per year. Anybody know if CK is actually worth it?
