This is off-topic for Community, so I will move it to the AA Forum.
As a DFW flyer, I also use the posted guides that
Efrem references above. I pretty much will walk if I'm in the same terminal or going from A to C, for example.
The TrAAin has victimized many a traveler with a tight connection... if you are that tight, you are better off flagging down a cAArt or just running!
(oh, and on a Community note, welcome to FT... we have a FTer already from Broken Bow, OK -
PeachesBB - and so now we have the other half represented!
