Kansas City International Airport (KCI; IATA: MCI) is KC’s primary commercial airport, located in the Northland approximately 18 miles northwest of downtown. It opened on November 11, 1972, and became internationally recognized for its “drive to your gate” terminal design — three semicircular horseshoe terminals where passengers stepped from curbside directly to their gate in seconds. After a decade of debate and a decisive 2017 public referendum, the original three-terminal complex was replaced by a single modern terminal that opened February 28, 2023.

History

From flood plain to the Northland

The push for a new KC airport began in the aftermath of the Great Flood of 1951, which inundated TWA’s facilities at Fairfax Airport across the Missouri River in Kansas. The flood made clear that a new airport site was needed on higher, flood-safe ground. In 1953 the city announced a site in Platte County — what would become the Northland — and construction of runways and a TWA maintenance base began in 1954. A precursor aviation complex (MCI) opened on that site in 1957, more than a decade before the passenger terminals arrived.

The passenger terminal complex opened on November 11, 1972, at 1:22 a.m., with a final cost of roughly $250 million after labor disputes drove overruns. The airport was initially named Mid-Continent International Airport (MCI) — the IATA code MCI survives to this day — and was later renamed Kansas City International Airport. It replaced Kansas City Municipal Airport (Wheeler Downtown Airport) as the city’s primary commercial aviation hub.

TWA and the drive-to-your-gate concept

When KCI opened, Trans World Airlines (TWA) was headquartered in Kansas City and envisioned the airport as its global hub, routing 747s and future supersonic transports through America’s heartland. TWA drove many of the key design decisions, most consequentially the “drive to your gate” concept.

Because Kansas City had very few connecting passengers — most travelers were origin-and-destination fliers — TWA pushed to minimize the distance between curbside drop-off and the aircraft door. The solution was a linear gate arrangement with roadway on one side and aircraft gates on the other. Architects Kivett & Myers, with engineering by Burns & McDonnell, gave this idea physical form in three semicircular terminals (A, B, C). Signs along the ring road showed which flights were departing from each gate; a passenger could be dropped off and board a plane in under a minute of walking. It was the first gate-arrival configuration of its kind implemented anywhere in the world.

Travelers widely admired the design for its ease, and airport planners cited KCI throughout the 1970s–90s as an alternative model to the massive hub-and-spoke megastructures being built elsewhere.

TWA’s tenure as the airport’s anchor carrier was, however, short-lived. After the September 11, 2001, attacks made the open-ring design incompatible with TSA security requirements — each gate would have needed its own checkpoint — and after Kansas City declined to fund major terminal reconstruction, TWA shifted its hub to St. Louis. TWA itself was acquired by American Airlines in 2001.

The long debate: renovate or replace

By the 2010s the three horseshoe terminals were aging, understaffed on concessions, and ranked near the bottom of mid-size American airports in national surveys. Airlines and civic leaders argued a consolidated terminal would attract more direct routes and international service. Defenders countered that KCI’s convenience was irreplaceable — and that any new terminal would erode the very quality that made the airport beloved.

The debate culminated in a November 7, 2017 citywide referendum. Kansas City voters approved a new single terminal by a margin of roughly 75% to 25%, one of the most lopsided airport votes in recent American municipal history. Design and construction planning began in 2018; ground broke in March 2019. Developer Edgemoor Infrastructure & Real Estate led the project with design-build partner Clark | Weitz | Clarkson.

The original terminal design

Terminals A, B, and C each followed the same horseshoe geometry: a curved roadway wrapped around the outside of the building, and aircraft gates lined the inner arc. The distance from car door to gate was measured in steps rather than minutes. There were no long concourses, no trams, no skyways — just a short walk through a security door.

The Brutalist-inflected structures — poured concrete, blocky massing, a spare geometric discipline characteristic of 1960s–70s American public architecture — drew less consistent praise than the passenger-experience concept itself. But the layout was the point: KCI demonstrated that an airport did not need to be a city unto itself to function well.

Terminal C was the last of the original three to close, winding down operations as the new terminal came online in 2023.

The new single terminal (2023)

The new terminal opened on February 28, 2023. At 1.1 million square feet and a final cost of $1.5 billion, it is one of the largest single capital projects in Kansas City history.

The terminal opened with 39 gates, with the facility engineered to expand to 50 as demand grows. A centralized TSA checkpoint — the security model that the old ring-road design could never accommodate — serves the entire building. The terminal includes a full concession program, consolidated airline ticketing, baggage claim, and ground transportation under one roof.

HNTB has served as a long-term engineering and planning partner to the Kansas City Aviation Department at KCI across the airport’s history, including work tied to the capital improvement program that preceded and informed the new terminal. Lead design architect for the new terminal was Skidmore, Owings & Merrill (SOM).

As of 2026, KCI is served by 13 carriers offering nonstop service to more than 56 destinations across the United States, Canada, and Mexico. Southwest Airlines and Delta Air Lines maintain the largest presences at the airport.
