Thanks for those links! Didn't know Amadeus had something similar.
Just like with Sabre, it seems all the "juicy" stuff is in the Enterprise API (which is opaque on pricing and setup -- you have to contact the sales team to get access).
Do you have any insight into whether it's possible for individual developers to get access to that enterprise API, and what the fees look like?
Would you have an example of a juicy stuff you are looking for? Seems to me most needs (flight search, seat maps, flight status, airport/airline infos) are covered by the self service API
