Abstract: 
The Flight Management System is a Java-based booking solution for flight tickets. It 
consolidates data provided by different airline carriers and hence provides the user details 
and rates in real-time. Travellers may want to make changes in their bookings. The 
application allows them to book, cancel, view and update their bookings with ease. Other 
than this, it eases the management of bookings too. All the bookings, flights, schedules and 
routes can be viewed, added and modified on a single application by the administrator. 
 

Scopes: 
Inscope: 
Following is the functionality provided by the system: 
 
There are two categories of people who would access the system: customer and 
administrator. Each of these would have some exclusive privileges. 
 
1. The customer can: 
a. Create his user account. 
b. Login into the application. 
c. Check for available flights. 
d. Make a booking. 
e. View the bookings made. 
f. Cancel or modify a booking. 
 
2. The administrator can: 
a. Login into the application. 
b. Add flight, schedule and route details. 
c. View the flight, schedule and route details. 
d. Cancel or modify the flight, schedule and route details.  
 
 
Outscope: 
The following functionalities have not been covered under the application: 
 
1. The application does not cover boarding pass generation and seating plans. 
2. Third party applications like email & sms integrations. 
3. Payments are not yet accepted by the application.

Validations:
1. The ‘userPhone’ should have an exact 10 digit number and the number should not 
start with zero. 
2. Date and Time should be valid i.e date and time that has already elapsed shouldn’t be 
entered 
3. ‘noOfPassenger’ should always be less than equal to that of available seats. 
4. The local part of the email should contain alphanumeric characters only. No special 
characters are to be present as the first character of the id. 
5. The chosen airport’s name should be present inside the Airport database. 
6. The Unique Identification Number should be of 12 digits. 
 

Assumptions:
However, we have made a few assumptions with respect to the application, which are: 
1. Administrator and customer are both Users. They are differentiated by a variable 
‘userType’ in the User class. 
2. Every passenger needs to enter a Unique Identification Number while booking is 
being made. For simplicity, we assume it to be a 12-digit Aadhaar Number. 
3. All flights are direct flights. 
4. No flight gets cancelled. 
5. Number of airports is fixed and stored in database. 
6. All the flights are considered to be domestic.
