What does it look like?

Use Case Scenarios – Request Available Flights NameRequests available flight information SummaryThe user provides a destination and dates to the E-Ticket Reservation System (ETRS). The system inquires the airline database about available flights and presents them to the customer. Basic EventsCustomerSystem 1. Launches ETRS application2. Displays UI for user to search available flights. 3. Selects origination city 4. Selects destination city 5. Selects type of flight (round trip or one-way) 6. Selects direct or nonstop flights 7. Selects flexible or specific dates of travel 8. Selects departure date 9. Selects departure time range

Use Case Scenarios – Request Available Flights 10. Selects return date 11. Select return time range 12. Submit criteria 13. Validates customer data. Data is valid if customer enters a start and end cities that the system provides service to and valid dates; such that the start date is not prior to the end date and vice versa. System only provides cities that it services 11. Shows list of flights that met customers criteria.

Use Case Scenarios – Request Available Flights ExceptionsCustomerSystem 1. If search criteria is invalid system displays error message. Invalid data is return dates before departure dates and/or the same departure airport and arrival airports 2. User acknowledges the message. 3. Displays UI with current criteria, allowing user to modify desired flight information; continues at basic event If data is valid and a flight cannot be found, the system displays a messages informing the user that no flights are available that met the current criteria.
