Terminal D at DFW has tons of shops and restaurants, and this thing. I’ve flown in and out of DFW many times over the years, and it’s really been amazing to see the renovations take place. They’ve managed to take a fairly crappy airport and turn it into something quite nice. I still hate having to take the train from terminal to terminal, it always seems I have to cross through three terminals to get to my connecting gate, no matter where I am coming from or heading to. But I do appreciate the comfort and conveniences and options available now it DFW.
Protip, it’s also a great place to connect when flying to Asia. I had a great flight on a brand new AA 787 from DFW to NRT.
