Hawaiian Airlines says it is taking control of passenger seat allocation on its American Samoa flights due to engineering parameters with the aircraft it uses on the service.
After a six-month study period, the airline found passengers on the route weighed 15 kilograms more than Federal Aviation Administration average.
This represents more than 100 kilograms per seven-seat row on the Boeing 767 used for the route.
The airline says this exceeds the manufacturer's 'ultimate floor loading' for the aircraft.
Hawaiian's Chief Operating Officer Jon Snook spoke to Dominic Godfrey about the aircraft's limitations.
