Tourism demand can be sharply seasonal
Beach destinations may peak in summer, while ski markets concentrate in winter. Operating outside those periods can leave too many seats chasing too few passengers.
Aircraft can follow demand around the network
A plane used for Mediterranean flying in July can serve warmer winter destinations later in the year. Seasonal planning helps airlines raise annual utilization.
Airport and staffing needs also vary
Ground handlers, seasonal crews and terminal capacity may be scaled around predictable peaks. Some airports are built around highly seasonal traffic patterns.
Frequency can change before a route disappears entirely
Airlines may move from daily service to weekends only, then suspend the route for several months. Capacity can therefore be adjusted in stages.
Events can create short operating seasons
Festivals, sporting events, cruises and school holidays can produce temporary demand strong enough for limited-period routes. Charter and leisure airlines use this extensively.
A seasonal route can still be strategically important
It may protect a market from competitors, support tour-operator contracts or feed a hub during peak periods. Year-round operation is not the only measure of success.
