Istanbul, Turkey: A Singapore Airlines Airbus A350‑900 service scheduled to fly from Istanbul Airport (IST) to Singapore Changi Airport (SIN) faced multiple departure failures this week, leaving hundreds of passengers stranded and prompting questions about operational communication and passenger handling during prolonged irregular operations. The long‑haul flight, originally scheduled as SQ391 on December 12, 2025 at 1:15 pm local time, was unable to depart on three successive occasions due to a recurring technical issue identified during pre‑departure procedures. The aircraft eventually departed on December 14 at around 3 am under a revised flight number SQ9391, arriving in Singapore later that day. Shortly after pushback on the first departure attempt, the flight crew reported a problem with the aircraft’s flaps, a key flight control component. The aircraft returned to the gate. All 229 passengers remained on board for nearly four hours as engineers conducted inspections and attempted repairs. During this time, food and beverages were provided. Efforts to resolve the fault extended beyond the initial delay, and the airline determined that additional time was needed for technical support and parts before safe continuation of service. Subsequent departure times were announced and later revised, resulting in three failed attempts before the aircraft was finally released. Passengers recounted frustrations over the prolonged delays and changing departure times. Some criticised the clarity and frequency of updates provided by airline staff at the airport. Although meal vouchers and hotel accommodation options were offered, several travellers reported challenges covering additional incidental expenses such as medication and extra meals during their extended stay in Istanbul. In response to media queries, a Singapore Airlines spokesperson reiterated that the safety of customers and crew remained the airline’s priority throughout the disruption, and offered apologies to affected travellers. The carrier also noted that assistance was provided in rebooking connecting flights at the final destination. In a separate incident, a Singapore Airlines long‑haul flight from Newark Liberty International Airport (EWR) to Singapore Changi Airport (SIN) carrying 151 passengers was delayed for more than 48 hours after its original departure on December 14, 2025, was postponed due to adverse winter weather and a runway closure for de‑icing. The flight, originally designated SQ21, was rescheduled and renumbered as SQ9021, but was delayed again due to an airport baggage handling system fault and a technical issue with the aircraft’s nose wheel, forcing further disruptions. The rescheduled service was subsequently planned to depart on December 16 and arrive in Singapore on December 17. Singapore Airlines, consistently ranked among the world’s top carriers, has reaffirmed its commitment to safety and customer care in its ongoing response to operational disruptions. The airline continues to support affected customers, reaffirming that technical rectification and passenger welfare are core priorities during irregular operations.
