Flight data systems require accurate airline information for display, validation, and business logic. Proper integration of airline data ensures correct information and good user experience.
Active vs Defunct Airlines
Airlines cease operations, merge, or rebrand. Historical flight data may reference defunct airlines. Your system should handle inactive airlines gracefully, displaying historical context or noting that an airline no longer operates.
Code Conflicts and Reuse
When airlines cease operations, their codes may be reassigned to new airlines. The same IATA code might have represented different airlines over time. Consider including operating dates when matching historical data.
Regional and Subsidiary Airlines
Major airlines have regional partners operating under their brand. United Express is operated by multiple regional carriers. Showing the operating carrier helps passengers know what aircraft and experience to expect.
