In the US, there has been a recent spate of headlines about turbulent flights. Guardian columnist Emma Brockes wrote this piece on the topic.

In March, a Lufthansa flight en route from Texas to Germany diverted to Dulles airport in Washington DC after turbulence injured seven people. Last December, a Hawaiian Airlines flight from Phoenix to Honolulu encountered turbulence so bad that 20 people required hospitalisation. In July, another Hawaiian Airlines flight, from Honolulu to Sydney, hit turbulence that injured seven people. In August, 11 people were hospitalised when a Delta flight encountered turbulence on its descent into Atlanta. The injuries included lacerations, head trauma, broken bones and loss of consciousness, mainly among passengers not wearing their seatbelts.
