It's been ages since I've flown thru Dallas and hope to never do it again. A couple of bad experiences.
1) An evening flight to Los Angeles, connecting from DFW to Burbank. The flight was late, they changed gates three times. This was also early on in the screening process when they also checked you at the gate. I had been up since 3 AM and it was going on 10 PM Central time. I was the "lucky one" chosen for a pat down. I bit my tongue, but really wanted to strip down to my underwear.
We also has an American Airlines flight from Phoenix with a connection in Dallas. One of the longest tram rides I've ever taken as we had less than 20 minutes to make the connection. Just made it as the doors were closing (they were paging us).
Throw in a couple of times when we flew in around Christmas and wished we had brought our own rock salt....
