Flights created or updated in Leon are **automatically transferred** to Flightkeys **via a secure API connection**. The exchanged data set includes: - flight numbers and sectors, - aircraft registrations and configurations, - planned times (STD/STA, block), - crew assignments and roles. Flightkeys builds its operational view directly on this data, applying its logic for conflict detection, crew legality checks, and real-time operational monitoring. When day-of-operations changes occur—such as delays, crew swaps, or aircraft changes—updated operational decisions can be synchronized back to Leon, keeping planning, dispatch, and operational records aligned within the **flight scheduling software** environment. ## One Operational Data Flow from Planning to Ops Control The integration establishes a single, consistent operational data flow between planning and day-of-operations. Flight data is entered once in Leon and reused in Flightkeys, reducing discrepancies between planning and operational control and ensuring both teams work with the same, up-to-date information generated by the **flight scheduling software**. By keeping schedules, aircraft data, and crew assignments continuously aligned, operations teams can respond faster to disruptions while maintaining crew legality and regulatory compliance. Planning and ops responsibilities remain clearly separated—planners work in Leon, ops controllers in Flightkeys—yet both systems operate on one shared data set. The connection is delivered via a **secure, scalable API**, transferring only the data required for scheduling and operational control. It is designed for complex airline and ACMI environments, supporting multi-fleet, multi-base, and high-frequency operations without adding manual workload. ## About Flightkeys Flightkeys is a privately held aviation software company headquartered in Austria, with a team of aviation engineers, flight operations specialists, and software developers bringing decades of airline and ATM experience. The company has been developing its technology platform for over a decade, combining deep domain expertise with modern cloud-native engineering. Flightkeys works with airline customers across Europe and international markets, supporting both regional and complex network operations. --- Not yet a member of Leon community?
