Airline Booking System
Architecting a Scalable GDS Flight Booking Engine with Domain-Driven Design and CI/CD Release Automation.
The Challenge
Airline booking engines process highly complex, fragile business rules covering seat inventory, dynamic pricing, and global GDS networks. Lime Management needed a scalable GDS travel reservation engine that could aggregate flight fare databases in real-time, handle flight search spikes, and automate partner group bookings safely.
The Solution
ClarvoTech built the AirFlex reservation platform. Leveraging our travel software development expertise, we architected the backend using C# and .NET Core based on Domain-Driven Design (DDD) to keep pricing logic isolated and maintainable. We built custom API connectors to sync with Global Distribution Systems (GDS) for real-time flight lists, and designed a group-booking portal to automate ticketing workflows.
The Process & Implementation
We structured the database using SQL Server with multi-region failover. To guarantee release safety, we wrote automated Selenium UI test suites to verify checkout paths. We set up an Azure DevOps CI/CD pipeline, automating code compilation, unit tests execution, and container deployments to ensure new features ship safely without breaking existing flight grids.
The Results Delivered
The AirFlex GDS platform launched successfully, boosting group-booking checkout completions. Automated Selenium tests ensure updates are deployed with zero downtime.
Business & System Impact
- 1.5-Second Flight Search: Parallel GDS queries process and filter seat options with minimal latency.
- Automated Group Bookings: Partners book flight blocks autonomously, cutting manual back-office tasks by 60%.
- Robust CI/CD Release Flow: Automated Azure DevOps pipelines reduce software update times and release errors.
