An American Airlines jet encountered severe air turbulence shortly after taking off from Seoul, South Korea, prompting an unscheduled landing at Narita International Airport in Tokyo after 14 people asked for medical attention.
The airline says four passengers and a crew member needed hospital treatment, but none of those injuries are life-threatening.
A statement issued by the Fort Worth, Texas-based carrier says American Flight 280 was headed for Dallas-Fort Worth on Tuesday when the Boeing 777-200 met with turbulence.
After the landing, passengers and crew members were evaluated and treated in Japan. American says there were 240 passengers on board and 15 crew members.
Officials say the remaining passengers won't continue their travel to DFW until Wednesday and have been taken to hotels to spend the night.
