Available Seat Miles

A measure of an airplane's ability to carry passengers. It is calculated by taking the number of seats available on the plane and multiplying by the number of miles the plane flies. Available seat miles are important because they are used to calculate the cost per available seat mile and the revenue per available seat mile, which are both used to help determine an airline's profitability.
