Rocks.

I did get the 75% bonus as a silver though.
I got to hand it to DL the promo actually worked on me. I had no plans of flying Delta unless they were way cheaper than all *A carriers, but I ended up getting rebooked on DL when a UA flight cancelled, and then since I was 1/3 of the way there, I booked one more 2 seg trip for this weekend and will be sure to fly a 2 more segments by 6/30.
Im such a sucker for this stuff, but I really do like the idea of having the ability to earn 100% RDM bonus on US, CO, UA, and DL for the rest of this year.
