In a bold move, European carrier Finnair has introduced a trial program at its Helsinki Airport hub where passengers are willingly stepping on the scale before boarding the plane. The aim of the program is to allow the airline to refine weight estimates for flights in order to improve aircraft balance and performance calculations. In an interesting twist, passengers are being weighed alongside their carry-on bags, reminiscent of the dreaded "crouch of shame" when trying to remove items to meet weight restrictions. However, traveler privacy is maintained as the weigh-ins are completely anonymous, with only the gate staff seeing the information.
The trial, which began on Monday, has already seen an impressive 800 volunteers participating by Thursday morning. Päivyt Tallqvist, Finnair's Senior Vice President of Communications, expressed the airline's positive surprise at the number of willing participants. The airline plans to weigh 1,200 passengers during the winter season and more during the summer. Finnair has reached out to its customers via social media channels and its mobile app to inform them about the survey, and some passengers even offered to participate before the equipment was set up.
The data collected through these weigh-ins will assist the airline in obtaining more accurate estimates of the average weight of passengers and their hand luggage. These estimates are crucial for calculating the overall weight and balance of the aircraft before each takeoff. While airlines already have data on the weight of other factors such as cargo and baggage, the weight of passengers and their carry-on bags is usually based on average weights provided by aviation authorities. Finnair currently uses its own measurements, but these need to be updated every five years.
Other airlines have also conducted weight surveys in the past. Korean Air implemented its own weighing program in 2023, and Air New Zealand conducted a weight survey last year. Finnair's program aims to collect data for both winter and summer seasons, as passengers tend to wear heavier clothing during the colder months. The winter readings will be completed by February, followed by the summer ones in April and May. The airline plans to calculate an average weight from the measurements and will submit the data to the Finnish Transport and Communications Agency for verification. This information will be used for loading calculations in the future.
To alleviate any concerns about privacy, Satu Munnukka, Finnair's Head of Ground Processes, emphasized that the collected data is not linked to customers' personal information. Only the total weight and background information of the customer and their carry-on bag are recorded, without any requesting names or booking numbers. The customer service agent managing the weigh-in is the only person with access to the total weight information. This reassurance allows passengers to participate in the study with peace of mind.
Overall, Finnair's trial program of weighing passengers before boarding the plane aims to enhance safety and operational efficiency by obtaining more accurate weight estimates. With this data, the airline can better calculate the balance and load distribution of the aircraft, which in turn affects seating arrangements, the number of passengers allowed onboard, and the amount of luggage that can be transported in the cargo hold. While privacy concerns may arise, Finnair assures passengers that their personal information remains protected throughout the process.
