Leaving Lambert

10 miles to the northwest of its downtown core is Rome of the West’s principal airport, the famous Lambert-St. Louis International. The airfield derives its name from the famous, local resident and former Olympic medalist Albert Bond Lambert, and it is currently a focal destination for Southwest Airlines. Lambert-St. Louis was previously a central flight hub for American Airlines and Trans World as well, and to date transports in excess of 12 million passengers per year.

The airport garnered international recognition in the 1920s due to being the site where famous American pilot Charles Lindbergh had his first piloting assignment, as well as its at the time critically acclaimed air traffic control and legendary terminal architecture. Affordable Wi-Fi, private banquet rooms, and many retail shops are available for passengers at the facility.
