On 16 January 2022, an Airbus A320 in cruise unexpectedly and very briefly encountered light clear air turbulence. Despite being secured in a seat, one passenger sustained a serious injury not assessed as such by the passenger or the cabin crew at the time, but which subsequently resulted in hospitalisation with a broken rib. The minor turbulence encountered had included a lateral movement which caused firm impact with the seat armrest. The operators’ response included amending the safety briefing and related procedures and introducing a new video on turbulence awareness to be shown immediately after the briefing.
