Thanks for the link.
I have seen that chart before, but couldn't find it again. It's very interesting. For me personally I am missing Thai and Singapore airlines. What about those 'elite' clubes within Singapore Airlines? I have read a bit how marvelous tehy are and soem of the perks they offer. Is it worth top move the program to SIA?
I have never flown Thai except BKK/SYD. Which is not the greatest choice in C. I still wonder how there FF programm may be.
