In this paper, we propose a new optimization strategy to increase reserve crew utilization and build monthly reserve crew work schedules by addressing the issue of scheduling conflicts and daily operational ... Airlines using a bidline system to award crew work schedules require additional reserves to cover scheduling conflicts, which result in trips dropping out of optimized bidlines. ... Gamache et al.
