The British flag carrier, British Airways (BA), offers flights to many cities in the US. The Anglo-American flights offered by the carrier comprised one of the most famous flight numbers in history- BA001. This service with this flight number from the Concorde is now retired, but BA still serves top destinations in the US such as Washington, New York, among others. British Airways is currently offering double Avios on flights. In this article, we will examine the top US routes by seat availability of this carrier.

British Airways operations between LHR and SFO have the highest number of seats on BA’s three routes with 63 operations for August. The only competing carrier from Britain operating direct flights on this route is Virgin Atlantic, which uses Boeing 787-9s on this route, while British Airways uses its Boeing 777s and Airbus A380s. These two British carriers compete with the sole carrier from the US offering services between LHR and SFO – United Airlines.
Two routes have 93 operations each, but there is a great difference in the number of seats available
Both the Heatrow (LHR) – and O’Hare International Airport (ORD) and LHR – Los Angeles International Airport (LAX) routes have 93 operations in August. However, the LHR-LAX route has around 8000 more seats. The LHR-LAX route also offers almost two times more ASMs. The 247 seats per departure on the LHR-ORD route is also the least seats per departure on this list.
