Singapore Airlines has adjusted protocol for its in-flight service, saying it will suspend meal service when the seatbelt sign is on and require crew members to return to their seats.
The new policy follows a May 21 incident during which a Singapore jet encountered severe turbulence that sent dozens to the hospital and resulted in one death.
The airline said it will "continue to review our processes as the safety of our passengers and crew is of utmost importance."
Flight 321 between London and Singapore was carrying 211 passengers and 18 crew when the Boeing 777 encountered severe turbulence over Myanmar. The aircraft was quickly diverted to Bangkok for an emergency landing.
Forty-four passengers and two crew members remain in a Bangkok hospital, the airline said Friday.
According to various media, Adinun Kittiratanapaibool, who heads Samitivej Srinakarin Hospital in Bangkok, said Thursday that 22 people from the flight had spinal injuries and six remained in critical condition.
