(2) DL (Amex) and US (Visa) offer credit cards with status mile bonuses for large annual purchases. I have read that US allows multiple credit cards, so three 10K status mile bonuses (for $75K in purchases) would give you Silver status.

I only found: for Amex delta platium, you'll earn 15,000 bonus SkyMiles® (5,000 of which are Medallion® Qualification Miles) the first time you make a purchase..where did u get this 10k status mile for 75k purchase?

thanks.
