Air New Zealand to weigh passengers before they board the airplane | CNN

The program, which Air New Zealand calls a passenger weight survey, is a way to gather data on the weight load and distribution for planes, the airline said.
“We weigh everything that goes on the aircraft – from the cargo to the meals onboard, to the luggage in the hold,” Alastair James, the airline’s load control improvement specialist said in a statement. “For customers, crew and cabin bags, we use average weights, which we get from doing this survey.”
Still, weight is a personal thing that not everyone wishes to disclose. In order to protect individuals’ privacy, the airline says it has made the data anonymous.
