This airline is weighing passengers before they board flights

Finland's national airline Finnair has been weighing some of its passengers before they board planes - but not for the reason you may think.

Some reports suggested this would become the airline's new normal, but in fact, the weigh-ins ran for a limited time and were totally voluntary.

The airline now uses European Aviation Safety Agency estimations from 2009, which it says gives the weights of passengers as 88kg for a male, 70kg for a female and 35kg for a child.

Sami revealed that the weight of their passengers change a huge amount between summer and winter because of the extreme difference in temperature.

Finnair did this to check its unique passenger population against weight estimates provided by the European Aviation Safety Agency, according to the airline's communications director Päivyt Tallqvist.

"The weight of the aircraft impacts on so many things", including fuel levels and the speed and balance of the aircraft, said Tallqvist.

The study will continue through spring 2018, Finnair said, because it wants to collect data when travelers are carrying heavy winter coats and when they are traveling lighter in warmer weather.

Their carry-on baggage is also being taken into consideration and passengers must carry it onto the scale with them.

Sami Suokas, manager of customer processes at Finnair, told the newspaper Helsinki Times: "We want to make sure we have the best possible data at our disposal also in this respect".

The last report, dated 2008-2009, recommended calculating 94 kilograms for male passengers and 75 kilograms for females flyers including carry-on luggage.

She added that the first set of results will enable the airline to determine the number of measurements required to ensure the statistical accuracy of the passenger and luggage weight data. We use them for every flight, and they're important for the aircraft's performance.
