The "Flight Booking System" is an intelligent and web-based transaction management application designed to provide immediate assistance to passengers for airline ticket reservation, flight scheduling, and seat allocation. The system uses Java Spring Boot framework for enterprise backendlogic, MySQL database for relational data integrity, and modern frontend technologies to offer seamless interaction. A search mechanism is integrated into the application, allowing users to instantly fetch available flights based on source, destination, and travel dates. When a booking transaction is triggered, the backend automatically manages seat inventories using strict transaction protocols to avoid double-booking errors. The proposed system aims to reduce booking response latency and enhance data accuracy during peak load hours. The system is highly scalable, secure, and can be easily implemented across distributed airline servers. Overall, the project demonstrates how Java enterprise architectures and relational systems ensure high concurrency and stability.
