With the continuous expansion of the airline fleet size and operating routes, airlines need to work out quickly the optimal flight recovery plan during massive delay cases. In order to improve the efficiency of operation control, an automatic flights adjustment method was explored. According to different objectives such as economic benefits and flights on-time performance, the optimal operation scheme can be worked out, and eventually the rapid and efficient deployment of flights was achieved. This paper analyses the main scenarios of flight recovery, establishes the key restriction, designs the basic logic of recovery and verification, along with the application of a large aviation transportation enterprise, cooperated with Sabre Solution company. The advantages, risks and shortcomings of the flight recovery system are summarized. The practice shows the recovery manager system(RM) can reduce recovery time by 2 hours, reduce average delay time of each delay flight by 30 minutes, cut down the corresponding cost by 20,000 yuan, and improve airline’s total flight on-time performance by 3%~5%.
