    Operations research (OR) has been used successfully in industry and its impact in today’s airline operations is significant. All major airlines plan their operations based on various OR models and algorithms including the important aspects of airline scheduling. However, operations do not always proceed as planned due to unforeseen disruptions which may lead to flight delays and customer dissatisfaction. Operations research methods can also be applied to the schedule disruption problems which results from irregular operations. The aim of schedule recovery is to get back to the original schedule (after a disruption) as soon as possible by means of re-scheduling the originally assigned flights. In this paper we use different approaches to recover the disrupted schedule. In the first approach we delay the flight(s) in the network without changing the originally planned aircraft and crew tasks whereas in the second approach we considered the recovery problem using the concept of disruption neighbourhood. The test instances are performed on real data on Air New Zealand’s domestic operations.
