MOTIVE OF THE PROJECT

7. • Electronically handling of flight’s
record to enhance the , flexibility,
reliability and to remove the human’s
error.
• To provide accurate information
about the addition, deletion and
modified records.
• its easy to make flight reservations
by sitting at home .

8. INTRODUCTION
This project on Airline Management System is the
automatic registering process of airline system.
The system is able to provide much information
like passenger’s information, list of all passengers
etc. The system also allows us to add records
when a passenger reserves a ticket. For data
storage and retrieval we use the file-handling
facility of C Language. It enables us to add any
number of records in our database. But for the

9. intrinsic nature of file handling,the retrieval
process is slow when we search a particular record
in the database, because records are searched
sequentially. This program shows you an insight
into the management process of reservation in
Airline Management system.
