For a one-time $400 score plus MR points, at the risk of being blacklisted from one of the top two card issuers for people who travel. Not a great strategy, really — especially since the banks will see it coming a mile away, after the blogs all beat the idea to death from now until December.
I've been doing this for quite some time now, including the points fiasco where AMEX really dropped the ball, and I'm still churning away without a blacklist. Everytime I call they thank me for my loyalty. Just the other day, I was approved for 2 Delta cards with another one pending. AFAICT, this blacklisting thing is a bit of a myth (as it relates to the activities I'm engaged in).
