SIA has meanwhile suspended the serving in-flight meals, in addition to hot drinks, when the seat belt sign is turned on, as part of a more cautious approach to managing turbulence.
The national carrier also diverted its daily London to Singapore SQ321 flights to avoid the airspace over the Irrawaddy Basin in Myanmar, where the sudden turbulence occurred about three hours before the scheduled landing earlier this week.
The two SQ321 flights since Tuesday’s incident instead flew over the Bay of Bengal and Andaman Sea, route data from flight tracker FlightRadar 24 showed. The flight time is about the same, according to tracking data.
