St. Louis Lambert International Airport

St. Louis Lambert International Airport, also known as Lambert Airport, is the primary commercial airport serving the St. Louis metropolitan area in the United States. It provides passenger and cargo air transportation services, facilitating domestic flights to numerous U.S. cities and international connections to destinations in Canada, Mexico, the Caribbean, and Europe. The airport hosts a variety of airlines, including major carriers and regional operators, and offers amenities such as terminal concessions, parking facilities, and ground transportation options. Its airfield consists of two parallel runways that support a mix of commercial, general aviation, and military aircraft operations. Lambert Airport also provides facilities for aircraft maintenance, fueling, and ground handling services that support the airlines operating there.

The airport is owned by the City of St. Louis and overseen by the Lambert-St. Louis International Airport Authority, which manages its day-to-day operations and long-term development. As a key transportation hub, Lambert Airport contributes to the regional economy by supporting tourism, business travel, and freight movement. Its distinguishing attributes include its role as a focus city for Southwest Airlines and its capacity to handle both civilian and military traffic due to proximity to the Missouri Air National Guard base. In October 2022, the airport experienced a website outage resulting from a distributed denial-of-service attack claimed by the pro-Russian hacker group Killnet, which temporarily disabled online services such as real-time parking occupancy checks while flight operations continued unaffected. The incident was part of a broader series of cyber disruptions targeting multiple U.S. airports, and the airport restored its website within hours after establishing a passenger information hotline. These characteristics underscore Lambert Airport’s position as a critical infrastructure asset within the national aviation system.
