Ahhh, yes... the 'just 180k' argument. Yeah, because there are so many DL flyers that have 200k+ of disposable income after taxes and put all of that on their Amex card. And you know what? If they're not flying then I don't care what status that person is, since they won't be competing for upgrades anyway.

If somebody wants to MS 200k on Amex cards and only get ~1% back, go for it. If DL wants to reward a small businesses owner with DM by putting 250k+ on their Reserve business card, then thats their prerogative as well.
