Kansas City International Airport (MCI) is the primary commercial airport serving the Kansas City metropolitan area in Missouri. Originally opened in 1972, it was designed with a unique three-terminal layout that allowed passengers to park very close to their gates, a concept praised for convenience at the time. In 2023, the airport opened a brand-new single-terminal facility, replacing the aging original terminals and modernizing the passenger experience significantly. The new terminal consolidates operations under one roof with updated amenities, improved security checkpoints, and expanded concessions. MCI serves millions of passengers annually and connects Kansas City to major domestic hubs as well as select international destinations. It plays a vital economic role in the region and has seen renewed investment following the terminal replacement project.
