Cost Reduction
Commercial airlines generally wish to keep the cost of a flight as low as possible. There are three main factors which contribute to the cost:
-
- amount of fuel needed (to complicate matters, fuel may cost different amounts at different airports),
- actual flying time affects depreciation charges and maintenance schedules etc.,
- overflight charges are levied by each country the aircraft flies over (notionally to cover air traffic control costs).
Different airlines have different views as to what constitutes a least-cost flight:
-
- Least cost based only on time.
- Least cost based only on fuel.
- Least cost based on a balance between fuel and time.
- Least cost based on fuel costs and time costs and overflight charges.
