For those that haven't been here, DFW is huge. I'm here 2, 4, sometimes 8 times a month and it grows on you. AA occupies 4 of the 5 terminals and the Skylink is a clean, fast and efficient way of navigating your way around. We arrived at C17 and a few minutes later were on the Skylink for the long winding way around to the D terminal. One would think C and D would be next to each other but alas the progression here is A, C, E, D, B and a blank space presumably for a future F.
The D terminal is the newest and most attractive terminal. It also serves as the main international terminal.
American has an Admirals Club in all four terminals. Been there, done that. So I was eager to visit the new Centurion Lounge. Amex is opening these lounges at a few airports (LAS and DFW so far). All one needs to gain entrance is an Amex Platinum or Centurion card.
