This will probably be great for me personally, if AC moves in any further direction towards what UA, AA, DL have done. I would be top tier on any of them.

As someone who doesn't actually travel all that often compared to many of you, but has otherwise quite shameful spending habits, I appear to be an airline's dream customer. Everyone pays very slightly higher prices at the store because of my fancy credit card, and because of that I get to fly J at a modest discount several times a year.
