I received the promotion today by mail. It's actually a very nice package. There's a very nice book included explaining the benefits and it was tailored specifically to this promotion. I don't know what number of offerees justifies such effort but it's clearly something that was well planned and that Delta is making a priority.

I'm Executive Platinum on AA and Mosaic on JetBlue and am quite happy with that (mostly because of AA).

I flew two Delta flights last year - short hauls in F. I'll probably do it just for the miles. I have no idea why I was targeted.
