How Does an Airline Reservation System Work?

When you are ready to start with an airline reservation system, one of the important factors here is the learning process of how this system effectively works.

Let’s check out the complete steps below. 

Step 1: Search and Input Details

It captures the origin, destination, date of travel, and number of passengers. The system starts to search for flights in real time based on the query. Many platforms also allow filters like direct flights, cabin class, or flexible dates that help users refine results quickly.

Step 2: Real-time Flight Availability Check

It connects to the core database or GDS of the airline and pulls live information. This ensures that the seat availability, routes, timings, and cabin classes are accurate at the instant of search. Nothing is cached; results reflect the real inventory.

Step 3: Fare Calculation and Display

Dynamic pricing rules calculate the cost of the ticket, considering demand, seasonal trends, class of travel, and airline policies, among other variables. Taxes and baggage options also come into consideration. To the traveler, a clear flight list appears, displaying final pricing and cancellation terms before making their choice.

Step 4: Flight Selection and Passenger Entry

When the user has chosen a flight, the system temporarily blocks the chosen seat to avoid overselling. The traveler inserts information such as name, contact, and passport information if the flight is international. The system will check the format and completion of all required fields so that the booking process will be smooth. 

Step 5: Payment and Ticket Confirmation 

Payment information passes through a secure gateway that approves or rejects card details. Once approved, the reservation is confirmed, and the seat is permanently removed from the airline's inventory. Unsuccessful payments return the seat to the system instantly, keeping availability accurate. 

Step 6: Creating PNR and Issuance of E-Ticket 

A unique PNR is generated with all flight and passenger data. The system emails or texts the e-ticket to the traveler, which gets synced with the airlines' check-in and departure systems. From here, passengers can check in, add baggage, or manage their trip with ease.

To create an airline reservation system, you should be well aware of the market, what’s in trend, their type, and how these are influencing the user’s preferences to book an airline.
