St. Louis Lambert International Airport (STL) — Airport Guide 2026

✈️ Terminals — Know Which One Before You Go

Lambert is two separate buildings. Terminal 1 is the one that photographs well — the historic domed terminal with concourses A and C, built in the TWA era and still the more atmospheric of the two. Terminal 2 is a newer, lower-key building used mainly by Southwest. They are linked by a free shuttle bus and by the MetroLink train, but they are not a walk apart — they are a drive apart. Get this right before you show up, especially if you are connecting or planning to use the Wingtips lounge in Terminal 2 while your flight leaves Terminal 1.

The airline roster: Southwest in Terminal 2; American, Delta, United and others distributed across both. The hub legacy is gone. STL is now a mid-size point-to-point airport that clears quickly outside the predictable morning and evening rushes.

🛂 Border & Visa

International arrivals process through CBP (US Customs and Border Protection) in the usual way. The volume of international flights at Lambert is modest — this is not an intercontinental hub — so lines tend to be shorter than at O’Hare or JFK.

Global Entry, Mobile Passport Control (MPC), and APC kiosks are available for eligible arrivals and meaningfully cut wait times. If you have Global Entry, use it. Visa-required nationals need their US visa sorted well in advance — there is no consulate workaround at the border.

The currency is the US dollar throughout Missouri. Tipping is expected — 18–20% in restaurants, more when service warrants it.

🚆 Getting Into the City

Lambert has something most American mid-size airports do not: a direct light-rail link that actually reaches the city centre.

Rideshare and taxis run about $40–50 for the same 25–30 minute trip. The distance (~22 km) means the train is consistently the cheaper option unless you have luggage-heavy reasons to skip it.

🛋️ Lounges

There is no separate airline-branded lounge at Lambert. Wingtips is the only Priority Pass option, and it is the only real lounge play in the building.

🍽️ Food Before You Fly

St. Louis has a genuinely local food vocabulary worth knowing before you get to the airport and settle for a chain.

Toasted ravioli is the thing most St. Louisans will point you toward — breaded, deep-fried ravioli, attributed to an accident in The Hill, the city’s Italian neighbourhood. It sounds odd and it works. Order it as an appetiser.

Gooey butter cake is the local dessert: a dense, intentionally under-baked coffee cake that leans sweet to the point of excess. A box of it is the correct carry-on purchase. It does not travel badly.

St. Louis-style pizza is the local flashpoint — cracker-thin crust, Provel cheese (a processed blend that divides opinion even among residents), cut in squares rather than triangles. Worth trying once; whether it counts as pizza is a conversation you can have on the plane.

Anheuser-Busch — the Budweiser brewery — is near the Soulard neighbourhood and runs tours. It is not inside the airport, but it is a reasonable stop if your itinerary allows.

Airport dining inside Lambert skews to standard US airport fare. Eat in the city if you have the time; stock the carry-on with gooey butter cake for the flight.

💡 The Gateway Arch Layover — Honest Math

The Gateway Arch is Eero Saarinen’s 192-metre stainless-steel catenary curve on the Mississippi riverfront — the tallest arch in the world, and the most recognisable object in the St. Louis skyline. There is a tram inside that carries you to an observation deck at the top. It anchors Gateway Arch National Park, beside the Old Courthouse. Forest Park — which is larger than Central Park — holds the free Saint Louis Art Museum, Zoo, and Science Center, and is a separate, longer excursion.

The layover math:

• 4–5 hours: Comfortable. MetroLink from either terminal to downtown takes ~38 minutes each way (free with boarding pass). That gives you time at the Arch, the riverfront, and a quick bite, with a 90-minute return-and-security buffer. The tram to the observation deck adds a queue; factor 20–30 minutes for it.

• 3 hours: Tight. Workable for a quick look at the Arch exterior and the riverfront if the trains align and you skip the tram queue. You will not have much margin.

• Under 3 hours: Stay airside. The transit time alone eats most of it.

Forest Park is a longer trip — the Art Museum and Zoo reward a half-day, not a 4-hour layover.

🧭 Practical Notes

• The MetroLink vending machines at the airport default to a $4.00 two-hour pass. Show a same-day boarding pass instead and ride free. Do not pay the $4 unless you have lost the boarding pass.

• Terminals 1 and 2 are separate buildings connected by a free shuttle bus and by the MetroLink. Know which terminal your airline uses before you arrive.

• Reduced-mobility assistance is free — arrange it through your airline before travel.

• International arrivals (the few that route through STL) clear US CBP. Domestic arrivals walk straight out.

• ESTA must be approved before flying, not on arrival.
