I'm going DFW. Lots of plusses for me:

1. Skylink is easy and generally quick to navigate
2. 5 ACs plus Flagship Lounge options
3. Just over 900 miles to CMH so I get a meal in F, and connecting to the west coast means two meals instead of one.
4. Big winner during IRROPS: Lots of assistance at ACs, many alternate flights and connections. Two Hyatts connected to the airport itself. Minute Suites in a pinch. Also if stranded overnight, it's a warm-weather city with direct light rail access to downtown.
