Cusco’ s airport (tel. 084/22-2611) is 10 minutes south of town and the taxi ride costs about US$2.50. Taxes for domestic flights are US$5.84 pp.
All Cusco-bound travelers must first arrive in Lima  and then board another plane in Cusco, for which there are currently three main operators. To approach Cusco’s airport, planes must fly at considerable altitude and down a narrow valley, passing ice-covered Nevado Salcantay en route. Because of the tricky approach and winds, afternoon flights are frequently cancelled. If possible, fly in and out of Cusco in the morning.
