Some interesting quotes-
"A parking lot at the airport's south end provides an existing and obvious footprint for a new terminal. But DFW's famed horseshoe design was laid out in the 1970s at a time when air travel was significantly different and didn't contemplate the type of mega-hub model favored by major airlines today."
"I wish it was an easy thing to say you just build another Terminal D on the F site," said Tim Skipworth, American's vice president of airport affairs and facilities. "But it's more complicated than that."
"While Terminal C was initially supposed to be part of that renovation, the airport held off work as it eyed future plans. The terminal, opened in 1974, consistently scores the lowest of any at DFW in customer experience surveys, and the airport's long-term plans will have to consider how to update or replace the facility and its 28 gates.
"I call C the LaGuardia of DFW. And I mean that. I'm not proud to say it, but I do," Donohue said, referencing the dated New York airport.
Merely updating Terminal C to bring it in line with other terminals would likely cost $1 billion or more, he said, with no added gates."
"Do you want to put $1.5 billion into a 50-year-old asset?" Donohue asked. "I don't believe that's the right answer. ...
"The existing plot that's now home to the Express South Parking lot would allow a new terminal to easily hook into the Skylink tram system and fit neatly with the five other terminals.
But building there would continue a design that dates to the 1970s and was aimed at making it easy for local customers to park, check in and walk to their gates in as short a distance as possible."
"That's less than ideal for the airport as it has evolved into a major hub for connecting passengers, which will be the largest driver of growth as American continues to add flights. Connecting passengers might have to take a tram to a different terminal to change flights, while the airline has to hustle to make sure checked bags make it to the correct planes."
"American and DFW Airport officials say they're looking at a range of options for a new terminal design, from something that closely mirrors Terminal D's mix of international and domestic gates to a modular approach that adds gates in phases to something that departs from the existing horseshoe designs altogether."
My opinion, if Terminal F was a Terminal D clone this process would have started already. The fact AA and the DFW are still talking leads to me to believe we are starting to see a new layout built in stages over the course of many years.
