Bertrand Lecocq, the pilot, said the rough air was likely from the remnants of the massive storm that just hit the northeastern U.S. Seven people had to be treated for injuries.The plane was carrying 192 passengers and a crew of 11, including eight flight attendants and three pilots, the airline said. “Three flight attendants and four passengers were transported to a local hospital for further evaluation,” American Airlines spokesman Ross Feinstein said. The most seriously injured person was a flight attendant, who was bleeding. The nature or seriousness of the injuries wasn’t immediately clear. “We are taking care of our passengers and crew, and we are working on next steps to get them safely to their destination.” the airline said. Passengers were processed through customs and hosted at the Delta Hotel in St. John’s overnight.
