Flight Pairing Optimization

Flight pairing, the process of constructing sequences of flights (pairings) that crews can legally and efficiently operate, is one of the most computationally intensive problems in airline operations. For a major European airline, the challenge was to generate optimized pairings across a dense, dynamic network of short-haul routes, within a tight planning cycle. The solution had to simultaneously respect hundreds of regulatory and collective agreement constraints, minimize operational costs, and remain robust enough to serve as the foundation for downstream crew rostering.

NukkAI provides an end-to-end solution, reducing planning time from days to minutes. We designed an engine that navigates the full complexity of real-world flight pairing and enforces every regulatory constraint without exception. We delivers results in record time, accelerating the whole pairing planning process and ensuring additional time for decision making.

• Automated generation of legal, cost-efficient pairings across the full flight schedule
• Simultaneous handling of hard constraints (FTL regulations, rest requirements, base constraints) and soft objectives (cost minimization, workload balance)
• Integration into client's planning workflow as a production-grade optimization engine
• Dramatic reduction in planning time: from 6 days to generate a pairing solution down to 5–10 minutes for an optimal result
