It's really quite ridiculous. I made the backend to a travel site using data from Galileo reservation system (one of the big ones). At the time, they had a relatively new SOAP-ish API. The data you got back was huge and arranged in ways that are not in any way obvious. Many calls just return what appear to be screen scrapes of 70's era terminal screens, wrapped in XML. It was less than fantastic.
At the time I left the travel agency in question, Galileo was in the process of rolling out a new version of the API, but the few times I tried to get it to work, it seemed completely broken (this was for cruises, not flights, but it was the same general idea).
