Kansas City International Airport (IATA: MCI, ICAO: KMCI, FAA LID: MCI) (originally Mid-Continent International Airport) is a public airport in Kansas City, Missouri, located 15 miles (24 km) northwest of Downtown Kansas City in Platte County, Missouri. The airport was opened in 1972 and a new complex in the airport was completed in 2023, replacing the old one. MCI replaced Kansas City Municipal Airport (MKC) in 1972, with all scheduled passenger airline flights moved from MKC to MCI. It serves the Kansas City Metropolitan Area and is the primary passenger airport for much of western Missouri and eastern Kansas.

The airport covers 10,680 acres (4,320 ha) and has three runways. The airport has always been a civilian airport and has never been assigned an Air National Guard unit. Since the 2020 pandemic shutdown, the number of peak-day scheduled aircraft departures has been steadily recovering. As of October 2022, there were 303 daily arrivals and departures. Nonstop service was offered to 47 airports, including Cancun, Montego Bay, San José del Cabo, and Toronto.
