Quickest way is to have a friend that is PM gift it to you but I realize the odds of that happening are slim. There is a sight I heard someone talking about once where some PM's were offering to sell their status but I have never found it (would actually be a good deal for me if I could sell it for over $200 for it, since I am planning on using my choice benefit for a $200 delta voucher LOL)

If you can charge $50K quickly, get a Platnium Delta Am Ex. You will get 5K MQMs for signing up and 20K mqms after charging $50k which is silver right there. Or if you can charge $60K a year get the delta reserve card, you'll get 30K mqms and the sign up bonus MQMs and if you are flyign delta enough that you want status your BIS miles would probably be enough to get you gold. You would also have skyclub access domestically and am pretty sure you would have access to the skypriority security lane and prem zone boarding even with no status with that card.
