Demand sets the broad capacity requirement
Planners estimate how many seats the market can absorb without depressing fares too far. Total weekly demand can then be divided among different combinations of aircraft size and frequency.
Schedule convenience can justify more flights
Several daily departures give customers flexibility and make same-day business trips possible. That can command stronger fares even if each flight uses a smaller aircraft.
Aircraft availability limits the choices
An airline may prefer three daily flights but lack the right small aircraft. Fleet structure can push a market toward fewer departures on a larger type.
Connections determine useful departure times
At a hub, flights are timed to meet arrival and departure banks. A frequency that looks unnecessary locally may feed important long-haul connections.
Slots and curfews can cap growth
Busy airports may not offer additional takeoff or landing times, while night restrictions can narrow the operating window. The airline may have to increase aircraft size instead of frequency.
Seasonality changes the answer
A route can support several daily flights in summer and one in winter. Airlines adjust schedules to preserve yield and utilization across the year.
