en.Wedoany.com Reported - British Airways, Europe's largest long-haul airline and a member of the oneworld alliance, maintains a strong position. According to Cirium Diio data, the airline currently operates an average of 90 long-haul flights daily from London Heathrow (LHR) and London Gatwick (LGW), a 2% increase year-on-year. This growth is driven by several new and resumed routes, including the inaugural flight from LHR to St. Louis, with British Airways also set to resume flights from LGW to Colombo later this year.

Based on OAG data, an analysis of British Airways' non-stop flights from July 2026 to March 2027 (data reflects known information as of June 16 and is subject to change) shows its longest block time is 15 hours 35 minutes, on the LHR to Santiago route. This one-way route covers 6,281 nautical miles (11,632 km) and is operated 3 to 4 times weekly by 215-seat and 216-seat Boeing 787-9s (the 215-seat variant features new Club World seats). British Airways previously served the Chilean capital via Buenos Aires until 2000 using the 747-400, with no flights on the route between 2001 and 2016, before resuming non-stop service in 2017.

Block time includes taxi time at both ends of the route, flight time, and brief delays, reflecting slot occupancy. It is measured from "chocks off to chocks on" (or gate to gate, gate to gate), aiming to balance competitive slot scheduling with high aircraft utilization and reliability. Due to the closure of Russian airspace, British Airways' multiple routes are forced to take detours, resulting in longer flight times. For example, flights returning from Shanghai Pudong International Airport (PVG) to LHR now have a maximum block time of 15 hours 5 minutes, compared to a maximum of just 13 hours 5 minutes in the four years before the Ukraine war. Flights now operate via Central Asia and the Caucasus in both directions. In contrast, Air China and China Eastern, which also fly between PVG and LHR or LGW, do fly over Russian airspace, with block times not exceeding 12 hours 45 minutes, meaning lower operating costs and a competitive advantage.

British Airways' 2nd to 5th longest non-stop flights are: 2nd place – PVG to LHR, with a maximum block time of 15 hours 5 minutes, operated daily by a Boeing 787-9; 3rd place – Tokyo Haneda to LHR, with a maximum block time of 15 hours, operated twice daily (Boeing 777-200ER from October, and Boeing 787-9 and A350-1000 before October and resuming in March); 4th place – Hong Kong to LHR, with a maximum block time of 14 hours 45 minutes, operated daily by an A350-1000; 5th place – Singapore to LHR, with a maximum block time of 14 hours 40 minutes, operated twice daily (Airbus A380 resumes in September), along with Boeing 777-300ER and Boeing 787-9 (before October and resuming in March), with the 777/787 continuing to Sydney. (Even counted once, as known as of June 16, subject to change.)

British Airways' sixth longest non-stop route is Kuala Lumpur International Airport (KUL) to LHR, with a maximum block time of 14 hours 5 minutes, operated daily by 215-seat and 216-seat Boeing 787-9s. This route is scheduled to be extended to Melbourne Airport (MEL) next January, and when combining non-stop and one-stop flights, it will become British Airways' second longest overall route. British Airways last served Victoria state in 2006. Fellow oneworld member Finnair will also soon launch flights to MEL, while Qantas will again offer a same-plane, same-flight-number service from MEL to Perth to LHR. Routes ranked seventh to tenth are: Bangkok to LGW (maximum block time 13 hours 20 minutes, 3 to 6 weekly Boeing 777-200ER); Mauritius to LGW (maximum block time 12 hours 35 minutes, 3 weekly Boeing 777-200ER); Cape Town to LHR (maximum block time 12 hours 10 minutes, 1 to 3 daily A350-1000, Boeing 777-200ER, Boeing 777-300ER, and Boeing 787-9); and LHR to Mexico City (maximum block time 12 hours, 5 weekly to daily Boeing 787-9).
