About this use case diagram for the airline reservation system

The subsequent use case diagram describes the airline reservation system used to successfully book flight tickets online. The system consists of three main actors, namely the passenger, the admin, and the bank. Each actor has distinct roles and privileges.

The admin has the authority to update the flight schedule and cancel any ticket, passengers have the privilege to check for flight availability, book a ticket, and pay for the ticket, and the bank will check the card details and confirm the transaction respectively.

As the passengers have the choice to select the seat they desire, therefore it has an extended relation with the “Select Seat” subsequently. Similarly, it is an important task to validate the card details with the bank, therefore it is related with an inclusion relation with the “Validate Card Details” module.

Using the use-case diagram, it has become easier to understand the relationship between all the components present inside the system and also recognize the include and exclude relationship amongst some of the system components accordingly.
