I've connected at DFW on AA twice in the past week and I must admit that my opinions about DFW have improved. It appears that AA now has enough elbow room with operations in terminals A B C and D... so the terminals themselves are not the jam-packed cattle pens they used to be. Skylink is an improvement over the older Airtrans people-mover system. Interior signage and aesthetics are okay not great. I noticed that many of the digital clocks have been removed so one can't tell with a glance while walking down the concourse what time it is... but that's a minor point.
