St. Louis Lambert International Airport (STL) — The Complete Master Guide 2026
St. Louis Lambert is the gateway to the Gateway City — the Missouri airport for the Gateway Arch, the Mississippi and the middle of the country. It sits about 22 km north-west of downtown, and it has the genuine advantage of a light-rail line with stations at both terminals running straight into the city. It is a no-single-hub airport now, with Southwest its biggest operator. The border is the US system — CBP for the limited international arrivals, ESTA for Visa Waiver travellers, , US dollars. This guide covers the MetroLink, that border, the lounge and the St. Louis layover.

🏢 1. The Terminal & St. Louis’s Two-Terminal Airport
Lambert runs two physically separate terminals — Terminal 1 (the historic domed terminal, with concourses A and C) and Terminal 2 (a newer building used mainly by Southwest) — linked by a free shuttle bus and by the MetroLink train. Make sure you know which terminal your airline uses, because they are a drive apart, not a walk. STL was once a major TWA and then American hub; today it has no dominant hub carrier — Southwest is the largest operator (Terminal 2), with American, Delta, United and the low-cost carriers across both. It is a manageable, mid-size airport that clears quickly outside peak.
🛂 2. The US Border: CBP, ESTA
- ESTA for Visa Waiver travellers (the UK, most of the EU, Japan, Australia and others), approved online before flying for visits up to 90 days.
- Global Entry, MPC and APC kiosks speed eligible arrivals; visa-required nationals need a US visa in advance.
The currency is the US dollar.
🚆 3. The MetroLink Red Line & Rideshare
STL has a real light-rail link, and it is unusually good value. The MetroLink Red Line has stations at both terminals (Lambert Main Terminal / Terminal 1 and Terminal 2) and runs to downtown St. Louis in about 38 minutes. The standard fare is $2.50 — but the local trick is that the ride is free with a same-day airline ticket (show your boarding pass), so keep it handy. Note the practical catch: the airport ticket vending machines sell a $4.00 two-hour pass rather than the bare $2.50 single, so the free-with-boarding-pass route is the one to use. Rideshare and taxis run about $40–50 (25–30 minutes) given the distance, so the train is far cheaper.
🛋️ 4. The Wingtips Lounge
STL’s Priority Pass lounge is the Wingtips Lounge in Terminal 2, a contract lounge with seating, Wi-Fi, drinks and a light food spread, accepting Priority Pass along with paid walk-ins. Because it is in Terminal 2 (the Southwest side), travellers flying from Terminal 1 should factor the inter-terminal shuttle if they want to use it. It is the main lounge play at Lambert; there is no legacy hub-flagship lounge since the hub era ended.
🍽️ 5. St. Louis Food Before You Fly
St. Louis has a distinctive, hyper-local food vocabulary. Toasted ravioli — breaded, deep-fried ravioli, said to have been invented in the city’s Italian neighbourhood, The Hill — is the appetiser to know. Gooey butter cake, a dense, sweet, under-baked coffee cake, is the local dessert, and St. Louis-style pizza (a cracker-thin crust with the local Provel cheese, cut in squares) divides opinion even among locals. The city is also the home of Anheuser-Busch (Budweiser), whose brewery near Soulard offers tours. For the carry-home, a box of gooey butter cake. Prices are in US dollars; tipping (~18–20%) is expected.
💡 6. Insider: the Gateway Arch & the Layover Math
St. Louis has one of the most recognisable monuments in America: the Gateway Arch, Eero Saarinen’s 192-metre stainless-steel catenary curve on the Mississippi riverfront, the tallest arch in the world, with a tram inside that carries you to an observation deck at the top. It anchors Gateway Arch National Park downtown, beside the Old Courthouse. Beyond it, Forest Park — bigger than New York’s Central Park — holds the free Saint Louis Art Museum, Zoo and Science Center, and the lively neighbourhoods of The Hill (Italian) and Soulard (the brewery and market) round out the city.
The layover math: the MetroLink Red Line is the key — about 38 minutes each way to downtown, free with your boarding pass, dropping you near the Arch. A four-to-five-hour layover covers the Gateway Arch and the riverfront with a 90-minute return buffer, helped by the cheap, direct train. A three-hour layover is tight but workable for a quick Arch visit if the trains align and you skip the tram-to-the-top queue. Under three hours, stay airside; mind that you may need the inter-terminal shuttle depending on your airline.
🧭 7. Practical Notes Before You Go
- Ride the MetroLink free with your boarding pass — show the same-day air ticket; the airport machines otherwise sell a $4 two-hour pass rather than the $2.50 single.
- Two separate terminals — know which one your airline uses; they are a shuttle ride apart, not a walk.
- this is the US. Limited international arrivals clear CBP; Visa Waiver travellers need an ESTA; domestic arrivals walk out.
- The Wingtips (Priority Pass) lounge is in Terminal 2 — factor the shuttle if you are in Terminal 1.
- Reduced-mobility assistance is free — arrange it through your airline.
