I got it as well. Here's my thing with DL...I enjoy flying them. They're a solid airline in the air, have a better F product than AS and I've generally had good customer service with them, plus I have the Platinum DL Amex for the companion ticket that comes with it.

But they're never going to be my primary for these reasons:

1. I live in ANC. I applaud them for beefing up their ANC-SEA schedule and adding year round FAI and JNU service but most of my travel is to PDX and IAH and AS flies nonstop/same plane direct.

2. Their absurd $200 change fee per ticket.

3. As has been discussed ad-nauseam on here, SkyMiles is just atrocious compared to Mileage Plan.
