I can tell you that it's not so easy to crack married segments when all airlines run their own programming . I have managed to crack some of them, some of them I play with all their systems . It has cost me several hours of insomnia. I'm looking for a professional who knows his business in Amadeus . I would gladly trade some ideas . It may be many different ways how I manupulate the most airlines' systems . I'm still working on cracking their RTIM . Who is eager to share ?
