Ops kid,. .. .In answer to your question, there are several fields available, Ops which depending on the setup of each airline can be computerised or manual, encompassing flight watch, flight planning, route creation, slot control and schedule adjustment. Pre ops would perform this function for flights between 3 and 30 days away.. .. .Crew control which can be more difficult, the name says it all, again on a day to day basis or at a stage post roster publication but pre release to day to day crew control.. .. .Roster creation (scheduling) again the clue is in the title.. .. .Most airlines have at least 2 levels in these fields, controller and assistant. Some airlines have other specialisations such as nav services or maintenance control (maintrol) lumped in with operations. As with operations sometimes the function of each position is computerised sometimes manual.. .. .Expect to start at the bottom I'm afraid.. .Hope this helps
