St. Louis Airport (STL) Terminal Guide 2026
St. Louis Lambert International Airport serves one of the Midwest's most important corporate and convention hubs. Two terminals, MetroLink light rail for downtown trips, and a sprawling suburban corporate corridor that rail can't reach. This guide covers every airline, the MetroLink options, when rail makes sense versus car service, and flat-rate pricing for Clayton, Chesterfield, the Arch district, and all St. Louis metro destinations.

STL has MetroLink light rail — but it doesn't serve the suburbs
STL Lambert is one of the few U.S. airports with direct light rail service. The MetroLink Red Line connects Terminal 1 to downtown St. Louis in 38 minutes for $2.50 (or free with airline ticket). However, MetroLink does not serve Clayton, Chesterfield, West County, Creve Coeur, Ballwin, or most suburban corporate campuses. If your destination is off the MetroLink corridor, car service is the practical choice.
STL Terminal 1 vs Terminal 2
STL has two passenger terminals connected post-security. Unlike many two-terminal airports, passengers cleared through security can walk between Terminal 1 and Terminal 2 via the secure concourse connector. This makes STL more convenient for groups or colleagues on different carriers arriving at different concourses.
Terminal 1
Concourses C, D, E
- American Airlines — primary carrier, connects to DFW, CLT, ORD, and PHL hubs
- United Airlines — ORD and IAH connections, EWR nonstop
- Southwest Airlines — Chicago Midway, Denver, Dallas, Nashville, Orlando
- Alaska Airlines — Seattle (SEA), Portland (PDX), Los Angeles (LAX)
- Spirit Airlines — Fort Lauderdale, Atlanta, Orlando, Las Vegas
MetroLink access
Lambert Main Terminal Station — Level 1
Lounges
Admirals Club (American, Concourse C)
Terminal 2
Concourse F + International
- Delta Air Lines — Atlanta (ATL) hub, New York (JFK/LGA), Boston, Minneapolis
- International arrivals — customs and immigration processed in Terminal 2
- Air Canada — Toronto (YYZ) and Montreal (YUL) seasonal
MetroLink access
Lambert East Terminal Station — Level 1 (walk via concourse connector or exterior)
Lounges
Delta Sky Club (Concourse F)
Post-security connection between T1 and T2
Unlike airports where terminals are completely separate, STL Terminal 1 and Terminal 2 are connected via a post-security corridor on Concourse C/F. Passengers can walk between terminals without re-clearing security. This is convenient if you and a colleague are on different airlines (e.g., American in T1 and Delta in T2) and want to meet before ground transportation.
