After severe air turbulence killed one person and injured many others, Singapore International Airlines announced a review of its safety guidelines.

New rules have been introduced to enhance passenger safety, specifically tightening regulations related to turbulence. The incident on Singapore International Airlines Flight SQ321 from London to Singapore prompted this review.

The turbulence, which occurred over the Irrawaddy basin in Myanmar, resulted in one British citizen's death and over 100 passengers injured, leading to an emergency landing at Suvarnabhumi International Airport in Bangkok.

The airline is reviewing its seatbelt policy, which currently allows passengers to unfasten their seatbelts after takeoff and requires them to refasten just before landing. This rule is under scrutiny. Additionally, the airline has suspended hot beverage and meal services when the seatbelt sign is on.

These measures reflect a "more cautious approach" to passenger and crew safety in response to predictions of increased turbulence due to climate change. Despite these precautions, passengers often resist wearing seatbelts throughout the flight.

Passengers on SQ321 described a terrifying experience, with many being thrown against the cabin ceiling before crashing back down. Doctors reported that the injuries were more severe than those typically caused by turbulence, including a spinal cord injury sustained by an Australian passenger. The airline continues to emphasize safety and is committed to ongoing reviews of its safety protocols.
