About this activity diagram for the airline reservation

This UML activity diagram depicts the functional flow of the activities in an airline reservation system. The UML diagram depicts how the user logs into the system, which is the first event in the reservations process. After logging in, the user goes to look for existing flights.

In case there are flights provided, the user can move forward, and choose any of the offered flights. After the user makes a choice, the system requests passenger info. This is a key part of the process, as it personalizes the booking. The user is then asked to pay after the information has been filled in. It is during this time that it is decided if the booking endeavor has been successful or if there are problems.

In the case that payment is made without a problem, then the concerned ticket is made by the application and it is emailed to the user. This action ends the reservation process. It guarantees the user will get all the info about their reservation. If the user fails to pay, the system will show a payment failure message.

If a search finds no flights, a notification is shown. This ends the process for the user. This ensures a smooth experience. The UML activity diagram for the airline reservation system accounts for all possible outcomes of interacting with the airline reservation system. This UML activity diagram shows a functional view of an airline booking system. It details the user interaction flow from login to ticket generation or a failure notice.
