External Interface Requirements of Flight Booking System VB Final Year Project
User Interfaces: System will provide the ability for users to access the AW online, view flight schedules, book tickets and make payment.

The user must be required to login in order to book a ticket and make payment, while for other purposes he need not be logged in.

He can view the status and schedule of a flight directly, tabs for which are provided on every page. The administrator will be required to log in at all times. However, they will have limit access via the web-interface only being able to pull predefined reports. 

The administrators will have to log in to a host machine inside the AW in order to build reports and ensure backups are running.
