Quito's Aeropuerto Internacional Mariscal Sucre is 37km east of the city in a broad valley near Tababela. It's a modern facility with the longest runway in Latin America and the second-highest control tower (after Cancun); however, the terminal is significantly smaller than Guayaquil's. A separate 'mall' with upscale dining options and cafes is across the porte-cochère from the departures drop-off.
