Why do airways weigh passengers?
Finnair is not alone in asking passengers to step on the size.
Korean Air equally introduced it could weigh passengers final fall at Seoul, South Korea’s Gimpo Worldwide Airport (GMP) and Incheon Worldwide Airport (ICN) because the airline sought to calculate the typical weight of passengers.

The apply — though controversial to many vacationers — is definitely pretty commonplace inside the airline trade.

Planes have most takeoff weights that may’t be exceeded, and in planning for a flight, airways have to think about something on board that may contribute to the takeoff weight — from the aircraft’s fuselage to the jet gas, gear, cargo and, certainly, the passengers themselves.
“If you do not have the suitable weight steadiness profile, a mistaken gust of wind — growth, you may drag the tail,” mentioned Blaise Waguespack, a professor at Embry-Riddle Aeronautical College who makes a speciality of airline advertising and operations.
Airways may additionally often weigh passengers to allow them to recalibrate the burden distribution of their plane to ensure that them to soundly take off and land, Waguespack famous.
Figuring out how a lot weight an plane can deal with might be necessary in conditions the place an plane is working in an space with sweltering temperatures, for instance.
Bob Thomas, an Embry-Riddle professor on the college’s aeronautical science division, mentioned in areas that may get extraordinarily scorching, airways might have to scale back the burden of their plane with a view to take off.
“Most individuals do not understand that the burden simply would not have an effect on your precise take-off distance, however it additionally impacts ensuring that you would be able to climb over obstacles afterward,” Thomas mentioned.
These measurements could show extra important for airways’ fleets of smaller plane, reminiscent of regional jets you could fly on to or from a smaller airport, the place every passenger’s weight could show extra important.
Do US airways weigh passengers?
Within the U.S., airways can even decide the burden distribution of planes from surveys carried out by the Facilities for Illness Management and Prevention.

So, some nations could require their carriers to have passengers step on a scale.

“This can be a authorities mandate and is critical for the protection of flight operations,” the spokesperson mentioned final fall.
Extra just lately, Finnair defined that it should gather new knowledge each 5 years and report it to the nation’s regulators to make sure future weight and steadiness calculations are on the mark.
The airline plans to rotate its upcoming weigh-in program round varied gates in Helsinki this month to gather mid-winter knowledge since passengers have a tendency to hold heavier coats and extra layers throughout the colder months. Then, it’ll do the identical in April and Could when the temperatures heat up.
Knowledge collected this yr will determine into the airline’s weight and steadiness calculations between 2025 and 2030.
And, relaxation assured, the airline says your data will stay confidential and nameless.
“We use the weighing knowledge for the typical calculations required for the secure operation of flights, and the collected knowledge isn’t linked in any method to the shopper’s private knowledge,” Finnair head of floor processes Satu Munnukka mentioned in a press release. “Solely the customer support agent working on the measuring level can see the entire weight, so you possibly can take part within the research with peace of thoughts.”
Backside line
It may well really feel disagreeable if an airline asks to your weight, however know that it’s a customary apply.
“It is undoubtedly a clumsy state of affairs, a clumsy dialog, a clumsy request,” Suckow mentioned, “however it’s one thing that the carriers have to determine the right way to do if requested by [regulatory authorities] to validate their program.”
