La traducción completa sería "tarifa por recuperación de gastos cobrados por concesión (de aeropuerto o terminal de transportes)", pero yo diría simplemente "tarifa por uso de aeropuerto/terminal". En realidad, se trata de una tarifa o cargo que la empresa de alquiler cobra al cliente final para recuperar los gastos que le cobra a su vez la concesionaria del aeropuerto o terminal. Teóricamente, este cargo no debiera aplicarse cuando el local de retiro/entrega se encuentra fuera de un área de concesión.
