A Singapore Airlines flight bound for Singapore returned to San Francisco International Airport on Oct. 14 after an unruly passenger caused concern on board. Flight SQ31 had been in the air for several hours when the pilots decided to turn back.

Singapore Airlines Makes a U-Turn
SQ31 departed San Francisco at 11:51 a.m. local time on Oct. 14, bound for Singapore. After the passenger incident developed during the flight, the pilots assessed the situation and decided to return to SFO. The aircraft landed safely at approximately 8:40 p.m. local time, nearly nine hour after its departure.
Singapore Airlines confirmed that the passenger had injured himself during the incident but did not publicly detail his actions. The airline said it was working with the relevant authorities following the aircraft’s return. The incident disrupted the journey for passenger traveling between the United States and Singapore.
Following the return to SFO, the flight later departed again at approximately 11:20 p.m. local time with a new crew. Singapore Airlines apologized for the inconvenience and said it was assisting affected passengers, including those who needed to rebook connecting flights. The airline also thanked passengers and crew members who helped managed the situation on board, reiterating that the safety of customers and staff remained its top priority.

Details of the Incident Remain Unconfirmed
Some online accounts have alleged that the passenger attempted to reach or open an emergency exit. However, those claim have not been independently verified, and Singapore Airlines has not confirmed them.
The confirmed details remain limited: a passenger became unruly, injured himself, and was handed over to local authorities after the aircraft returned to San Francisco. The incident highlights the operational disruption that an onboard safety concern can cause on a long-haul flight, potentially affecting passengers’ onward travel plans even when an aircraft lands safely.
