Yes, I know DFW very well. I like that airport a lot. A good place to spot aicrafts landing is the Marriott Hotel near the airport, if they land on RWY 17L. I've been there many times because I have my aunt who lives in Dallas. Although I always fly American regardless of where I go, I have never been through DFW just for a connecting flight. I go to DFW always for the reason I mentioned above. Like we all know, DFW is American's super mega hub. You don't see that many 767's there, still a few 727's, two or three 777's on a whole day, no NG737's yet, but you see a lot of 757's and MD-80's, especially MD-80's. Sometimes if you look carefully, you can see a whole bunch of Super 80's taxiing in line one behind the other, or waiting in the middle of the tarmac like a group of birds standing on the ground close to each other. It's unbeleivable! DFW doesn't look like it's busy because it's a very big airport in terms of area. This airport handles over 60 million passengers a year. I'm sure that at least two thirds of that fly American.
Doug, good luck in your new job at DFW.
