Isn't it great that one question can be answered with so many diverse perspectives! I agree with nearly everyone here, all for the reason that everyone has a different agenda when accumulating points. As this is a Frequent Flyer forum, I think it's a given that most of us fly annually for some reason or another. And the programs we gravitate to, are an extension of that agenda - whether it be cheaper airfares, upgrades, lounge access or simply retail gifts.
Whatever your points churning passion, being a part of any (or many) FF program will always be advantaged by joining the conversation on this website. I've found so many new unidentified friends here who can always steer me in the right path when I get confused. And it's actually made me confident to fly more each year. I would NEVER have experienced Business Class if it wasn't for the knowledge of seasoned pros on these pages.
Thanks everyone! I've got more points now than I know what to do with, and another year of flying in the pointy end to look forward to - all because of YOU x
