Demand is more than population size
Airlines look at who is likely to travel, when they travel and what they may pay. Business demand, tourism seasonality, visiting-friends-and-relatives traffic and connecting flows can all support very different route patterns.
Airport costs can change route economics
Landing charges, passenger fees, ground handling, terminal costs and incentive programs vary considerably. A secondary airport may be farther from the city but still attractive if it lowers the airline cost base enough to support cheaper fares.
Slots and congestion can block otherwise good routes
At a constrained airport, an airline may struggle to obtain a departure and arrival time that works commercially. A technically available slot at an inconvenient hour may be far less valuable than one aligned with business demand or connecting banks.
Aircraft capability sets practical limits
Runway length, elevation, temperature, navigation equipment and local operating restrictions can affect payload or aircraft choice. An airline may prefer another airport if the intended aircraft cannot operate efficiently from the first one.
Network airlines think about connections
A route may be valuable because it feeds long-haul flights rather than because the local market is large. Timings are often designed to connect into arrival and departure waves at a hub.
Airports also compete for airlines
Airport operators market their catchment areas, offer start-up support and present traffic data to carriers. A new route usually emerges from negotiation as well as passenger demand, and it may be tested seasonally before becoming year-round.
