Once again- I generally don't recommend this, but if you want to book a Delta award (or SQ award until May 15), there is a 25% bonus from now until June 30. I actually have a family member who might be able to take advantage of this for a DL metal trip, but the "4-6 weeks" after the promo ends to post the bonus miles is ridiculous. And Delta is notorious for poor point posting.
