Emergency Landing of British Airways Boeing 787-9 in Sydney
A British Airways Boeing 787-9 Dreamliner conducted an emergency return to Sydney Kingsford Smith International Airport (SYD), Australia, on September 8, 2025. The flight crew declared a mayday after detecting a fuel odor in the cockpit.
The aircraft landed without further issues. It vacated the runway five minutes post-landing as a precautionary measure.
Details of the Incident
The Boeing 787-9, registered as G-ZBKL, was en route as flight BA16 from SYD to Singapore Changi International Airport (SIN) when the incident occurred. Upon detecting the fuel smell in the cockpit, the crew donned oxygen masks and declared a mayday, which led to a safe return to SYD. The passengers were informed of the reason for the return by the crew. After the incident, the aircraft remained at the Sydney airport.
The aircraft was scheduled to continue its journey from SIN to London Heathrow Airport (LHR) but the subsequent flight was canceled. On September 9, 2025, the route was operated by another Boeing 787-9, registered as G-ZBKS.

Typical Operations and Route
British Airways primarily uses its 787-9 aircraft for long-range flights from its London Heathrow (LHR) hub to Asia-Pacific destinations like Singapore, Kuala Lumpur, Shanghai, Delhi, and Tokyo Haneda. It is also tasked with some shorter routes from LHR, such as to Dubai.
The airline’s only flight to Sydney operates daily via Singapore as flight BA16 on a Boeing 787-9. The departure from Sydney is scheduled for 14:40 local time, arriving in Singapore at 21:00, with a subsequent flight from Singapore to Heathrow leaving at 22:40 and arriving at 05:25 the next day. This itinerary spans 16,655 kilometers or 8,992 nautical miles. Service to Sydney was resumed in April 2022 after a hiatus caused by the COVID-19 pandemic.
Fleet Utilization Adjustments
Between November 2022 and March 2023 and again in other similar periods, British Airways replaced the Boeing 787-9 with the larger Boeing 777-300ER on the Sydney route. The latter offers 254 seats compared to the 787-9’s 216. The switch was repeated during the Southern Hemisphere’s summer months, aligning with the travel trends from the United Kingdom for sun-seeking vacations.
