The "Seat Factor" is a measure used in the transportation industry, particularly in aviation and public transit, to assess how efficiently a vehicle is being utilized. It is calculated by dividing the number of seats filled by the total number of available seats, expressed as a percentage. A higher seat factor indicates better utilization of capacity, which can lead to increased revenue for airlines and transit operators. For example, if a flight has 150 seats and 120 passengers, the seat factor would be 80% (120/150 x 100). Monitoring the seat factor helps companies like airlines and bus services optimize their operations and improve profitability by adjusting routes, schedules, or pricing strategies.
