Amadeus Altea

Amadeus Altea is the passenger service system Amadeus supplies to airlines, covering reservation, inventory and departure control, within a portfolio that also serves airports, border authorities, corporate travel and travel sellers.

A passenger service system is the operational core of an airline and among the most demanding systems in commercial computing. It holds every booking, decides how many seats may be sold at what fare, manages check in and boarding, and must do so continuously, because an airline cannot stop selling or stop boarding while a system is unavailable. Migrations between these platforms are famously difficult and occasionally very public failures.

Inventory is the part outsiders least expect to be complex. An airline does not simply sell seats, it manages fare classes, overbooking against expected no shows, connecting itineraries and interline agreements, and the revenue consequence of getting that wrong across a network is substantial.

Serving airports and border authorities from the same portfolio reflects that a passenger journey crosses several parties who must exchange data reliably, and holding those systems in one place reduces the integration between them.
