I'd venture that the average 15 year old will do a better job navigating DFW than many if not most of the travelers passing through. "Changing planes" is substantially less challenging than most navigating required for beginning and ending journeys there.

1. Skylink is your friend.

2. The big "maps" on the walls are for real, and should be scrutinized (as should the big screen ARR/DPT boards, which generally reflect gate changes which are neither as frequent or as "terminally" complex as some suggest).

It's been a long time since I was 15, but I still on occasion murmur a prayer of thanks to my parents who raised me as curious and willing to learn by looking and inquiring. I must admit to some trepidation to sending our youngest daughter off to Paraguay when she was 16, but she seemed to deal with MIA better than I often have.
