According to Wikipedia it seems like a lot of people use or used ITA: “This system has been and is used by travel companies such as Bing Travel, CheapTickets, Kayak.com, and Orbitz, and by airlines such as Alitalia, American, ANA, Cape Air, Delta Air Lines, United Airlines, US Airways, and Virgin Atlantic.”

That's the shopping engine, which was successful, but only a small subset of what a TPF reservation system does...albeit one of the more complex pieces.
ITA did build the full thing, but only Cape Air used it. The "full thing" being shopping, schedules, inventory, booking, cancel, change, check-in, etc.
Oh interesting so ITA is really just a retail front-end for TPF then? I guess I was misinformed about it as well.
The customers shop using ITA. The ITA shopping engine gets schedules, inventory and updates inventory from/to the backend (often TPF).
The shopping engine itself isn't trivial. ITA has the best shopping engine available.
I was under the impression that ITA used exclusively Common Lisp to inplement their software. I could be wrong, though.
