Good cross-post. This is a big enough promo that it applies to everyone, not just NW fliers.
The question I have is -- can you take one flight, move in 40,000 points from diners, and get Platinum status?</font>
Read the terms of the promotion. The max you can get is 5000 miles. Diners is not an eligible partner for the promotion.
