Mariscal Lamar International Airport (es|Aeropuerto Internacional Mariscal Lamar) is a high elevation airport serving Cuenca, the capital of the Azuay Province in Ecuador. It is named after the Peruvian military leader and politician José de la Mar, a native of Cuenca.
Since 2002 the Instrument landing system (ILS) for the airport has been fully operational. The airport is in a high elevation basin within the Ecuadorian Andes, with mountainous terrain in all quadrants.
Despite improvements, the location of the airport in the middle of the city is a major handicap, as the runway is only barely long enough for large planes landing at this altitude. This has resulted in accidents involving planes running off the end of the runway, and a restriction on flights in wet weather during much of 2016. The airport has completed a runway resurfacing to improve traction in wet weather.
