Finnair has just begun a new program where it weighs passengers before take-off to help the Finnish airline collect more accurate data about weights on its flights.

Paivyt Tallqvist, director for media relations at Finnair, confirmed that the airline was weighing passengers on Tuesday and Wednesday at the Helsinki airport.

"So many people actually wanted to take part in this," she said, noting that the weigh-ins are voluntary and anonymous. "No one is forced on the scale."
