Line maintenance including a comprehensive range of services from A checks and scheduled engine changes, through cabin cleaning and servicing, AOG service and total care programmes relating to cabin maintenance, particularly in-flight entertainment systems, on-wing engine support, LRU exchange programs and overnight checks with an efficient use of ground time, is the future. This future will be evolutionary, dictated by economics.
