(CNN) -- Eleven people on an Air Canada flight from Sydney, Australia, to Vancouver, Canada, suffered minor injuries when the Boeing 777 flew through turbulence Friday morning, the airline said.
The plane made an unscheduled landing in Honolulu, Hawaii, an hour later so passengers, crew and the aircraft could be checked, an Air Canada statement said.
Nine passengers and two flight attendants were treated for minor injuries, the airline said.
All but two of the passengers and the two injured flight attendants reboarded the plane, and the flight to Canada resumed after a two-hour delay, it said.
The "seat belt" sign was on at the time of the turbulence, the airline said.
