St. Louis Lambert International Airport
(or “Lambert,” as it is commonly called) rose to prominence in the early 20th century thanks in part to its association with famous aviator Charles Lindbergh. Lambert currently offers flights from 14 different air carriers and is a major hub for low-cost air carrier Southwest Airlines, which, as of 2018, accounts for more than 61% of passenger flights out of the airport. American Airlines, for which Lambert was formerly a hub, is the second leading airline at Lambert. Lambert is also connected by light rail to MidAmerica St. Louis Airport, another commercial airport serving the St. Louis area.
