What affects domestic airfare?
The real factors behind domestic airfare: demand, inventory, timing, and route structure.
Quick answer
Domestic fares are driven by demand against a ladder of fare classes: booking window, day and season of travel, route competition, airport alternatives, and how full the cabin already is. There is no fixed schedule — prices reprice continuously with inventory.
Exceptions and quirks
- Adding a stop can cost more than a nonstop on odd dates
- Nearby airports on the same metro can differ dramatically
- Basic economy can look cheapest while costing more after bags and seats
