Beginning Monday, passengers flying on Korean Air could also be requested to step on a scale earlier than boarding their flight.
The train, which can final about three weeks, is required by regulation and applies to all Korean flag carriers, a Korean Air consultant instructed CNBC.
The regulation requires airways to weigh passengers and their carry-on baggage at the least each 5 years and is “essential for security of flight operations,” the consultant instructed CNBC.
The announcement was met with backlash from the general public, in keeping with native media.
A discover detailing the train — set to start at Gimpo Worldwide Airport Monday, adopted by Incheon Airport subsequent month — has been eliminated from the airline’s web site, attributable to “ample discover and media protection,” in keeping with the airline.
Is it affordable to weigh passengers?
“Positively not,” mentioned Vance Hilderman, CEO of the aviation security firm Afuzion.
No less than not for the aim of security, he mentioned.
“When you’re at a small Bombardier, a small Embraer jet, and we had 10 very overweight individuals … it might make a small distinction,” he mentioned. “On business plane, something from a 737 and above you already know, 120 individuals, we have now it inbuilt.”
Aviation software program can alter for weight adjustments, air density and different elements, which is why security is not compromised even in conditions the place passenger make-up is atypical, reminiscent of an early morning flight of largely businessmen, who are likely to weigh greater than the typical traveler, he mentioned.
Total, a big weight enhance per passenger can be eclipsed by the burden of gasoline, cargo and the plane itself, mentioned Hilderman. “Gas is 20 occasions greater than the passenger weight,” he mentioned.
Moderately than specializing in passenger weight, it is extra essential to regulate for added cargo and the variety of passengers on board, mentioned Afuzion CEO Vance Hilderman.

However Shem Malmquist, an teacher at Florida Tech’s School of Aeronautics, mentioned random weight samples are a good suggestion.
“We use common weights of passengers, however persons are getting loads heavier,” he mentioned. “300 people who weigh greater than common can put an airplane considerably over weight, and all of our efficiency calculations — runway size, climb, impediment clearance, touchdown distances, altitude capabilities — all are depending on weight, amongst different issues.”
Hilderman agrees that persons are getting greater, however he mentioned passengers now differ in different methods too.
“Individuals are getting heavier. So are Chinese language, so are Koreans,” he mentioned. “However we’re additionally flying youthful … so it is truly offset the typical human’s weight enhance.”
A research printed in 2019 within the Journal of Transport & Well being discovered that areas with larger weight problems prevalence “could start to see considerably compromised security margins if rising weight traits proceed.”
Jose Silva, an affiliate professor at Australia’s RMIT College’s Faculty of Engineering and one of many research’s authors, instructed CNBC that he thinks airways are reluctant to weigh passengers because of the delicate nature of the subject.
“There may be additionally a lack of knowledge of the security beneficial properties which could possibly be obtained if there have been extra correct means to establish the passengers’ weight, as an alternative of counting on requirements,” he mentioned.
A whistleblower criticism filed in 2021 alleges that the U.S. Federal Aviation Administration has failed to acknowledge questions of safety brought on by counting on common passenger or baggage weights that not mirror the U.S. inhabitants.
The place airways weigh passengers
Finnair did the identical in 2017, and Hawaiian Air has performed a number of passenger weight workout routines on flights between Honolulu and American Samoa. (The now defunct Samoa Air used to cost passengers by their weight, in keeping with Reuters.)
Flyers in the US possible will not be weighed, mentioned Hilderman, though an FAA advisory round printed in 2019 said that airways can weigh passengers.
It is a totally different story in Europe, the place carriers comply with European Union Aviation Security Company (EASA) rules.
American airways comply with rules set forth by the Worldwide Civil Aviation Group, which doesn’t require that passengers be weighed, mentioned Hilderman.

EASA weighed practically 23,000 passengers in 2008 and 2009 and located that common passenger weight had elevated by 3 to five kilograms (6.6 to 11 kilos). A subsequent report printed in 2022 discovered that imply passenger weight elevated barely since 2009, for a mean of 82 kg (181 kilos) for males and 68 kg (149 kilos) for girls.
Periodic weight assessments — of passengers and different gadgets on board — may help airways decide if weight estimates are nonetheless correct to offset the quantity of cargo they carry, mentioned Hilderman.
However “there’s slightly extra to this thriller,” he added.
“In Europe, they’re slightly extra rigorous about particular person rights with privateness,” he mentioned. “With EASA, they need to defend the passengers and say: Look, the passengers are getting bigger, so airways, we would like you to offer a minimal pitch distance in your seats.”
Industrial airline seating is predicated on common passenger weight from the Fifties to Nineteen Seventies, Hilderman mentioned. Since then, individuals have gotten greater, however airline seats have dwindled, he mentioned — “29 inches in some circumstances, it is completely ridiculous.”
A hot-button subject
Passenger dimension on planes is a controversial subject — with outsized flyers lodging discrimination allegations over Lilliputian airplane aisles and seat sizes, and smaller vacationers publicly venting about seat encroachment.
However in contrast to different industries that service heavy individuals — from makers of chairs to bogs to amusement park rides — the airline trade hasn’t enlarged seats.
“Some have proposed that overweight passengers be required to pay for 2 seats with the intention to not make different passengers uncomfortable, however that lets the airways escape any accountability,” mentioned Nick Gausling, a client providers enterprise advisor and managing director of Romy Group LLC.
Gausling famous that whereas different industries have been pressured to prioritize buyer expertise, “shoppers have little or no option to take their enterprise elsewhere” relating to airways.
Tigress Osborn, the manager director of the Nationwide Affiliation to Advance Fats Acceptance, instructed CNBC that the majority main airways have responded with three choices for obese vacationers: pay for pricier tickets that include greater seats, buy a second seat, or keep dwelling.
“Fats individuals should journey for pleasure similar to everybody else, and we additionally must do not forget that air journey is for work, for household obligations, and for different obligations, too,” she mentioned. “Our taxes assist help this trade, and we should be accommodated safely and comfortably, with entry to accessible seating in any respect value ranges.”
Concepts to assist bigger passengers
Hilderman mentioned airways can promote second seats to plus-size vacationers at a closely discounted fee.
As individuals have gotten greater, airline seats have shrunk, which has led to frequent complaints from air vacationers of all sizes.

Or they will reserve half a dozen seats for bigger individuals, which passengers might privately register for on-line, utilizing top and weight particulars from their driver’s licenses, he mentioned.
These seats could possibly be bought at a small surcharge, and if not booked by certified passengers the week earlier than the flight, launched to anybody prepared to pay for them, he added.
Any hope for wider seats?
As as to if airways will enhance seat sizes for everybody, Hilderman mentioned that whereas it is mathematically potential, it isn’t sensible.
“Fuselage diameters have been predetermined,” he mentioned, referencing the primary physique of the plane. “We at present have 29,000 business plane flying, and we solely make about 1,500 per yr, so it could take 20 years to interchange the whole fleet.”
Refitting planes with wider seats means narrowing the aisle, which is already a decent squeeze, he mentioned. To widen the aisle, one seat from each row would must be eliminated, leading to a 20-25% ticket value enhance throughout the board, he mentioned.
“Most individuals do not take a look at what sort of plane they’re flying, they usually do not know what the seat pitch or width is,” mentioned Hilderman. “They’re merely shopping for on value — and the airways know that.”
Arnold Barnett, a administration science and statistics professor on the MIT Sloan Faculty of Administration, instructed CNBC that the majority flyers are prepared to endure present seat sizes in return for decrease fares.
If seating modified, “airfares must go up, and flying would turn out to be unaffordable to passengers on restricted budgets.”
For a lot of, a decent airline seat is healthier than a seat on a bus, he mentioned.
