1. Schedule Development Process Given a set of routes to be operated in an airline network, and a fleet of aircraft, schedule development involves Frequency planning (how often?) Timetable development (at what times?) Fleet assignment (what type of aircraft?) Aircraft rotation planning (network balance) The process begins a year or more in advance and continues until actual departure time: Frequency plans established first, based on routes and aircraft Timetables and aircraft rotations defined 2-6 months in advance Final revisions and “irregular operations” until the flight departs
