Since you do SPG, look at the rules for their Crossover program with DL. A DL AmEx credit card can get you not only MQMs for status (or rollover if you make at least Silver) but also a MQD waiver for the newish spend requirements for status. Crossover benefits are best if you have elite status on both sides.
