Four people aboard a Japan Airlines flight to Honolulu sustained injuries Thursday when their aircraft experienced heavy turbulence, said JAL spokesman Winston Lee.

An ambulance and airport fire crew were on hand when the JAL Flight 74 touched down at Honolulu Airport, said state Department of Transportation spokesman Dan Meisenzahl.

He said the ambulance transported a 24-year-old woman and a 58-year-old woman to Straub Hospital. The younger woman suffered a bruise to her face and complained of pain to her elbows and hips. The other woman complained of pain to her head, hips and legs.

Meanwhile, a 38-year-old woman, who sustained a bruise to her head, and a 41-year-old man, who complained of pain to his head and neck, received treatment for their pain at the airport and refused transport, Meisenzahl said.

Lee said the 24-year-old woman is a JAL cabin crew member while the others are Japanese visitors.

He said the crew member was treated and released from the hospital yesterday and flew home Frday. The 58-year-old woman underwent surgery and is recuperating at Straub, Lee said.
