St. Louis Lambert Airport (STL) is set to welcome flights from a second European destination later today, marking the airport’s first nonstop connection with the UK in more than 20 years. This new service from London Heathrow will be operated by UK-based British Airways as the first nonstop flights from the British capital since American Airlines back in 2003.

The carrier is also set to deploy its premium-heavy Boeing 787 Dreamliner jets on this route, an indication of the type of market the airline is hoping to capture. With the launch of this service, British Airways strengthens its position in the highly competitive US – UK market, with STL becoming the airline’s 26th destination in the US.

Later today, British Airways will be operating its inaugural service, connecting its hub at London Heathrow Airport (LHR), with St. Louis Airport in Missouri. According to FlightRadar24, this will be the airline’s 26th US destination, while LHR will become the second European destination STL will be connected with going forward, complementing Lufthansa’s service from Frankfurt.

The schedule filed shows that this route is seasonal and is scheduled to operate only four times a week, on Tuesdays, Wednesdays, Fridays, and Sundays throughout the northern summer season, until October 24. The airline will be using the following itinerary (all times local):

As explored below, the airline will be using a mix of its Boeing 787-8 and 787-9 aircraft — interestingly, this will include its 204-seater, premium-heavy configured 787-8 jets, suggesting British Airways sees high potential for premium passenger demands and the associated higher revenue.

While British Airways flies all three variants of the Dreamliner family, this route will only see select Boeing 787-8 and larger Boeing 787-9 jets. While the smaller 787-8 is configured with three cabin classes – business, premium economy, and economy, the 787-9 is configured in a four-class layout, which also includes first class.

The 787-8 can accommodate a total of 204 passengers split into 31 business class seats (1-2-1 layout), 37 premium economy seats (2-3-2 layout), and 136 economy seats (3-3-3 layout). The 787-9, on the other hand, can accommodate up to 216 passengers in eight first-class seats (1-2-1 layout), followed by 42 seats in business class (2-3-2 layout), 39 premium economy seats (2-3-2 layout), and 127 economy seats (3-3-3 layout).

Over the past few years, the airline has been rolling out cabin upgrades across its fleet in an effort to modernize its product. Aircraft such as the 787s have been receiving refreshed premium economy cabins. Furthermore, as part of the retrofit program, the airline’s business class seats will also see upgrades, with some aircraft types, such as the Airbus A380, select Boeing 777s and 787s, still offering an older seat product.

Further Connections From St. Louis

Before today, St. Louis had just a single nonstop European connection – Lufthansa’s service from its Frankfurt Airport (FRA) hub. This launched in 2022 and initially ran with three weekly frequencies, but has proven successful enough for a ramp-up to five weekly flights this summer. Lufthansa’s load factors averaged at around 94% during the summer 2024 and 2025 seasons, benefiting from St. Louis’ status as one of the most German-influenced cities in the US.

As with most of the transatlantic flights operated by British Airways, when considering a destination to launch flights to, the presence of airline partners is key. In this case, British Airways will be looking to partner with fellow oneworld alliance members or carriers with which the airline has independent codeshare partnerships.

When considering St. Louis, the airline has the capability to provide strong onward connections within the US and the wider North America region. Its main partner is American Airlines, as the two carriers have a long-standing Transatlantic Joint Venture (JV) in place, enabling collaboration on this route and onward connections on either end. The second airline passengers could benefit from is Alaska Airlines, as both carriers are part of the oneworld alliance.
