Flight booking is the process of purchasing an air ticket and reserving a seat for a particular flight. A common scenario involves several main steps:
- Flight search,
- Choosing and booking a flight and ancillary services,
- Ticketing, and
- Check-in and departure.
At the second stage, the traveler (or agent) sends a booking request to the airline’s central reservation system to check the seat availability and price. If the seat is available, the traveler’s personal details are collected to create a Passenger Name Record (PNR) and enable ticketing.
Ancillaries such as additional baggage, meal choice, or seat preference can be selected in the course of the booking process or added later.
