Airline metrics are key performance indicators used to evaluate the efficiency and effectiveness of an airline's operations. Common metrics include load factor, which measures the percentage of available seating capacity that is filled with passengers, and on-time performance, which tracks the punctuality of flights. These metrics help airlines assess their operational success and identify areas for improvement. Another important metric is yield, which represents the average revenue earned per passenger per mile. This helps airlines understand their profitability and pricing strategies. By analyzing these metrics, airlines can make informed decisions to enhance customer satisfaction and optimize their services.
