Learn Amadeus the way agents actually work: on the keyboard.
DonaTrainer is a free, browser-based Amadeus cryptic terminal. No fake quizzes, no slideshows — you type the real commands, in a sandbox that talks back like the real system does.
A sandbox with real consequences, minus the risk
Everything here behaves like a live GDS — because that's the only way muscle memory actually forms.
The ultimate sandbox
Book, break, and rebook without a client ever finding out. Every mistake here is free tuition.
Real-world chaos, on demand
Schedule changes queue themselves for action just like they do on a live system — you'll learn to work a queue, not just a keyboard.
Built for the community
Free, forever, open-source. Our gift to every aspiring agent who can't get terminal access on day one.
