Airport guide
St. Louis Regional Airport sits on the bluffs above the Mississippi River in Alton, Illinois, roughly 20 miles from downtown St. Louis. It handles no commercial airline traffic, which means no congestion, no slot requirements, and ramp access without the delays that come with Lambert-St. Louis International. For private charter passengers heading to St. Louis, the metro area's north side, or the Illinois riverfront communities, KALN is a practical alternative to Lambert.
Aircraft Services Group operates at the field and handles FBO services including fuel, ramp handling, and aircraft parking. The airport is uncontrolled during off-hours, so coordination with the FBO ahead of arrival is advisable for after-hours operations. No customs or immigration facilities are available on-site, so international arrivals must clear at a designated port of entry before landing here.
Getting there
Downtown St. Louis is approximately 20 miles southwest, a drive of 30 to 45 minutes via IL-140 and the Clark Bridge or IL-3 south, depending on traffic and which bridge you take across the Mississippi. The Gateway Arch and Busch Stadium are both within that range. Car rental is not available at the airport, so passengers should arrange a car service or rental pickup in advance. The Alton riverfront and surrounding Madison County communities are within 10 to 15 minutes by car.
