At least 35 people suffered minor injuries after an Air Canada flight hit a severe patch of turbulence, the BBC reports.
The plane – which had 284 people on board – was travelling from Vancouver to Sydney on Thursday but had to be diverted to Hawaii.
Medical staff examined the injured after it landed at Honolulu’s airport at 06:46 local time (16:46 GMT).
The Boeing 777-200 jet “encountered sudden clear air turbulence… two hours past Hawaii”, the airline said.
It added that it was arranging hotels in Honolulu until a new flight to Australia could be arranged.
