Overview
Gateway to the Midwest and famous for its soaring stainless-steel Arch, St. Louis is a friendly, affordable American city that rewards curious travellers. Whether you're drawn by the Cardinals' baseball culture, the free-to-enter Forest Park museums, or simply a stopover on a wider US road trip, flights to St. Louis from the UK are more straightforward than many people expect, with good onward connections from all the major US hub airports.
Best time to fly to St. Louis
Late spring (April to June) and autumn (September to October) offer the most comfortable weather, with mild temperatures and lower humidity than St. Louis's notoriously hot, sticky summers. Winters can be cold with occasional snow, but fares often dip in January and February outside the Christmas period. For the best value, check the When to book chart above to see how fares typically move across the year before you commit to dates.
Airlines and routes
There are currently no nonstop flights from the UK to St. Louis, so travellers connect via a major US hub. American Airlines (often in partnership with British Airways) routes via Charlotte, Dallas-Fort Worth or Chicago O'Hare, while United Airlines connects through Chicago O'Hare or Denver, and Delta typically routes via Atlanta or Detroit. The transatlantic leg from London takes around 8-9 hours, with a further 2 hours or so on to St. Louis, meaning a realistic total journey time of roughly 12-15 hours including connection time.
Things to do in St. Louis
Once you land, St. Louis has plenty to fill a short break or a longer stay:
- Gateway Arch National Park: Ride the tram to the top of America's tallest monument for sweeping views over the Mississippi River.
- Forest Park: Bigger than New York's Central Park, home to the free St. Louis Zoo, Art Museum and History Museum.
- City Museum: A wildly inventive indoor-outdoor playground built from salvaged architecture, popular with families and adults alike.
- Missouri Botanical Garden: One of the oldest botanical gardens in the US, with beautifully landscaped seasonal displays.

At St. Louis Lambert International Airport (STL)
STL sits around 14 miles (about 30 minutes by road) northwest of downtown St. Louis. The MetroLink light rail runs directly from the airport into the city centre and is the cheapest option, while taxis, rideshares and car hire desks are all available in the terminals for a quicker door-to-door transfer.
Top tips for finding cheap flights to St. Louis
- Book roughly 2-4 months ahead of travel for the strongest chance of a good fare on the transatlantic leg.
- Flying midweek (Tuesday or Wednesday) is usually cheaper than weekend departures.
- Keep your dates flexible where possible and compare a few days either side using the price charts on this page.
- Compare carriers and connection cities, as routing via Chicago, Dallas or Atlanta can produce very different fares for the same dates.
Travel essentials
UK passport holders need a valid ESTA (Electronic System for Travel Authorization) for stays of up to 90 days under the Visa Waiver Program; apply online before you travel and keep the confirmation with your passport. The currency is the US Dollar (USD), so budget in pounds and check exchange rates before you go. No special vaccinations are required for entry, though it's always worth checking the latest NHS travel health advice before departure.
