Seriously
So it's not that big of a deal to get DM, but ya you will have to spend some coin on amex and delta and sit your butt in a seat, but that's the reason they make it this way; to make you want DM and spend money.
So then, grab a cobranded amex/delta plat and reserve card. Spend 60k on the reserve and 50k on the plat and POW, you got a waiver to PM and 50 mqms. Then what? Fly like 50k with 50% upgrade mqms and POW your a DM.
So can everyone stop complaining about how hard it is to hit DM please? It's not hard if you spend and fly, that's the whole point .
