"Korean Air will be measuring the averageweight of passengers along with their carry-on items for flight safety," South Korea's flag-carrying airline posted on its website, saying the move follows local laws.

Airline employees will weigh passengers for domestic flights from Gimpo Airport in Seoul South Korea from Aug. 28 to Sept. 6, Korea JoongAng Daily reported. They will also weigh passengers at Incheon International Airport from Sept. 8 to 19.

"Korea Air will weigh passengers along with other airlines in Korea to provide data required by Korea's Ministry of Land, Infrastructure and Transport (MOLIT) to update its "Aircraft Weight and Balance Management Standards," the airline released in a statement.

The outlet reported airlines are bound to calculate standard passenger weights every five years, and that the average helps determine weight distribution on airplanes.
