In this scenario, flight customers book a flight trip in the Web application of a travel agency. The flight customers first have to look for a suitable flight connection for the outbound flight and, optionally, for the return flight. Once suitable flights have been found, the customers must then identify themselves as customers of the travel agency before the flight trip can be booked. If they are new customers, they have to register with the travel agency and then each set up a Web user. If the customers have already registered, they have to log on as a Web user with the corresponding password (see also the scenario Administration of Customer Data). The customers then have to enter the necessary information to book the flight trip (flight class, name, and date of birth of the passengers), and can arrange for the flight trip to be booked.

1. Get flight connection list for outbound flight and, optionally, for return flight (function: Get Flight Connection List)
2. Get details for selected flight connections (can run more than once) (function: Get Flight Connection Details)
3. Manage customer data (see scenario Administration of Customer Data):

1. (For new customers)

2. (For new customers without a Web user) Set up Web user (function: Set Up Web User)
3. (For registered customers)
   Log on to the Web application (function: Check Web Password).
