Alternatively, suppose American Airlines must decide whether to continue to offer this particular flight next year. If American Airlines decides to cancel this flight because very few passengers during the last have taken it, the many more of its costs, including crew costs, baggage-handling costs, and airport fees for the flight, would be considered variable: Over this longer 1-year time period, American Airlines would not have to incur these costs if the flight were on longer operating. Always consider the relevant range, the length of the time horizon, and the specific decision situation when classifying costs as variable or fixed.
