Singapore Airlines (SIA) says it has taken "a more cautious approach" to managing turbulence during a flight. Not only will hot beverage services be stopped, it will also suspend meal service. Crew members must now buckle up when the seatbelt sign is on. SIA says it will continue to tell passengers to do the same during turbulence. The airline adds that it will continue to review processes.
