ABSTRACT
The discussion in earlier chapters was focused on airline operations at airports. This chapter extends the discussion of airline operations to a network level with the introduction of enroute flight operations by airlines, focusing on two main areas, namely crewing and fleeting. Key issues of crewing and fleeting are discussed in Sections 4.1 and 4.2, including setting up crew bases, regulation limits of working hours, aircraft maintenance requirements and routing aircraft for maintenance needs in a network. The complexity emerging from the synchronisation between flights, fleets, crew and passenger itineraries is discussed in Section 4.3 from the perspective of airline operations.
