Singapore Airlines flight SQ31 turned back over the Pacific Ocean on Wednesday, 14 October 2026, after a passenger became unruly, forcing the crew to return to San Francisco (SFO) after nearly eight hours in the air.
The incident involved an Airbus A350-900, registration 9V-SJC, scheduled to operate from San Francisco to Singapore (SIN). According to One Mile at a Time, what followed was a remarkable demonstration of airline logistics under pressure, as Singapore Airlines managed to despatch a replacement crew and get passengers on their way the same evening.
What Happened on Flight SQ31
The A350-900 departed San Francisco at 12:49 PM local time, approximately one hour behind its scheduled 11:45 AM departure, with the taxi alone taking close to an hour, as One Mile at a Time reports. The aircraft climbed to 36,000 feet and flew west across the Pacific for around four hours before the crew made the decision to turn back.
The plane touched down back at San Francisco at 8:32 PM local time, 7 hours and 43 minutes after it first departed, according to One Mile at a Time.
The Passenger Incident
A Reddit user who claims to have been seated several rows from the passenger in question described the scene to One Mile at a Time: "About 3 hours into the flight, this dude started screaming, kicking seats, and even tried to get to the emergency exit. He wouldn't stop yelling and kicking even after being restrained. Flight ended up diverting back to SFO, where the FBI and SFPD boarded and arrested him."
Singapore Airlines' crew determined that returning to San Francisco was the safest course of action. Authorities boarded the aircraft on arrival to remove the passenger.
Why San Francisco and Not Somewhere Closer
One Mile at a Time examined whether an alternative diversion point might have been more practical. The flight was tracking well north of Hawaii, making that island group an unsuitable option. Tokyo would have added at least a couple of hours of flying. Anchorage may have been marginally closer, and the Aleutian Islands, while geographically nearer, would not represent a suitable destination for an A350 unless the situation were life-threatening.
San Francisco was therefore a reasonable, if lengthy, choice under the circumstances.
Singapore Airlines' Rapid Turnaround
After the aircraft arrived at the gate at 8:41 PM, the same Airbus A350-900 was pushing back again by 11:19 PM, departing at 11:49 PM under the flight number SQ9031. That is a window of just over two hours in which the airline dealt with authorities, changed the crew, and re-catered the aircraft, according to One Mile at a Time.
The original crew had timed out after operating the near eight-hour return sector. Singapore Airlines operates at least two daily flights to San Francisco, and One Mile at a Time notes the airline appears to have drawn on a crew already in the city, likely cutting short a layover while keeping rest requirements met.
What This Means for Passengers
Passengers on SQ31 faced an extremely long and disruptive day. After landing at 8:32 PM and eventually departing again just before midnight, those continuing to Singapore endured many hours of additional waiting on top of the four-hour outbound sector they had already flown.
One Mile at a Time acknowledges the journey was gruelling for those on board, while crediting the airline for avoiding the more common outcome of an outright cancellation and overnight rebooking.

The Bottom Line
This incident is a reminder of the disruption a single unruly passenger can cause: in this case, a transpacific Airbus A350-900 burned fuel for nearly eight hours without reaching its destination, and scores of passengers lost most of a day. The response from Singapore Airlines in assembling a fresh crew and getting the replacement service away inside two and a half hours was, by any measure, operationally impressive.
