Mariscal Sucre International Airport

Mariscal Sucre International Airport (UIO) is Ecuador's busiest airport and one of the highest-elevation international airports in the Americas, sitting at 7,841 ft (2,400 m) above sea level in the Tababela valley 18 km (11 mi) east of Quito's colonial centre. The current facility opened in February 2013, replacing the previous inner-city airport that had operated in a shrinking urban basin since 1960 and whose short runway effectively capped payload for long-haul flights. The new 13,445-ft (4,098-m) concrete runway 18/36 - one of the longest commercial runways in Latin America - was engineered to offset thin high-altitude air and permit fully loaded Boeing 787 and Airbus A350 operations. Operated under a 35-year concession by Quiport, UIO serves 54 routes to 29 destinations on 26 airlines (2026), with home carriers LATAM Ecuador, Avianca Ecuador and Equair providing the regional backbone and long-haul links to Madrid (Iberia, Air Europa), Amsterdam (KLM), Atlanta (Delta), Houston, Miami and Panama City. The airport is also a critical logistics hub for Ecuador's fresh-flower industry: nearly 80% of the country's export roses leave the Andes as air cargo through UIO, much of it on dedicated freighters to Miami. UIO handles roughly 6 million passengers annually and has been repeatedly recognised by Skytrax and ACI for service quality within Latin America, including being named South America's Leading Airport multiple years. The new Eastern Access highway, completed in 2014, cut the previously lengthy transfer from the city centre and enabled the airport to function as a true secondary hub for Andean and U.S.-Latin America traffic. The airport is named after Antonio José de Sucre, hero of the Battle of Pichincha and independence from Spain in 1822. Ground-handling and fuel operations are notably complex because of the altitude: turbine engines lose about 20% of sea-level thrust, runway ground-roll extends by roughly 40%, and payload on some westbound U.S. routes is restricted on the hottest days.
