St. Louis lands another route to Europe as British Airways adds 27th US city

British Airways is setting its sights on St. Louis.

Next spring, the U.K.-based carrier will launch nonstop flights from St. Louis Lambert International Airport (STL) to London’s Heathrow Airport (LHR).

The new flight, set to launch in April 2026, will give travelers in the St. Louis region a second nonstop route across the Atlantic, three years after German carrier Lufthansa launched nonstop service from STL to Frankfurt Airport (FRA).

The new Heathrow flights will also offer a new way to both reach London and connect to an extensive array of destinations across Europe, Africa and the Middle East served by British Airways and its partners.

As for British Airways, STL will be the carrier’s 27th U.S. airport.

How to book British Airways with points and miles

Travelers hoping to book British Airways flights with points and miles have a ton of options.

If you’re a U.S. traveler with a large sum of American Airlines AAdvantage miles, you can use those to book seats on British Airways, since the two airlines are partners in the Oneworld alliance (just watch out for taxes and fees, which can run quite high on London trips).

Alternatively, a myriad of credit card and/or transferable currency programs allow you to move points directly to British Airways Club, including:

While Citi ThankYou Rewards doesn’t offer direct transfers to British Airways, you can move points to Qatar Airways Privilege Club — which uses the same Avios award currency — and then use a free tool to transfer those Avios to British Airways.
