Several European airlines have started weighing the passengers and their bags.
Finland’s flagship carrier, Finnair, said it will begin collecting data about its customers’ weight starting February and running through May.
The company said it will use the information to improve flight safety.
Over 500 passengers have already volunteered to participate in the study, which the company says is voluntary.
The data collected will not be used for any other purpose and will be kept confidential.
Satu Munnukka, a Finnair official, noted that the company uses the information collected for the calculations that are required for flights.
The company does not ask for personal information about the passengers, such as their names or booking number.
It only collects the total weight of their bags and the passenger’s background.
A customer service agent can view the total weight of the bag at the weigh-in counters at the Helsinki Airport.
According to Finnair, flight balance calculations involve the weight of the plane, its cargo, fuel, onboard catering, and passengers’ baggage.
The Civil Aviation Authority of Finland can also provide airlines with their own estimates.
About five years ago, Finnair conducted a similar study, which was able to gather data about the passengers’ weight.
Other airlines, such as Korean Air and Air New Zealand, also asked their passengers to weigh in.
