Passenger Service System (PSS)
The PSS comprises three main modules.
- An airline or central reservation system contains information on schedules, fares, and reservations, manages booking requests, generates PNRs, and issues tickets.
- An airline inventory system controls the availability of seats and manages fare groups.
- A departure control system manages passenger-related activities in the airport, e.g., processing check-ins, controlling baggage, printing boarding passes, etc.
Additionally, a PSS can include such optional components as a revenue management solution, retailing platform, and an NDC offer and order management platform.
The top-three providers of comprehensive PSS solutions that together hold about 60 percent of the market are Navitaire, Amadeus Altéa, and SabreSonic.
