Fiji Airways has completed investigations into an incident where passengers on a Nadi to Los Angeles flight fell sick mid-flight.

Fiji Airways Acting Chief Executive David Bowden says they’ve ascertained that neither Fiji Airways nor catering company Air Terminal Services is to blame.

“The ATS Catering which is our service provider has been exonerated. The origin of the sickness did not stem from the actual carrier. It happened prior to the passengers boarding the aircraft.”

12 passengers suffered diarrhea and vomiting and paramedics had to attend to them on board the plane.

The passengers affected had been staying at the same resort before catching the flight to the US.

The resort in question was informed of the incident.
