On one airline, a trip in flight will also involve a trip to the scale.
Uzbekistan Airways announced recently it would begin pre-flight weighing of passengers to determine the average weight of passengers and their carry-on luggage.
It appears that the procedure is strictly for research purposes and will aid the International Air Transport Association (IATA) in ensuring flight safety. Passengers will be asked to proceed through a weighing machine in the departure gate zone.
The record of passenger weights will remain anonymous, according to the airline. Instead, weights will be categorized by gender or age, if the passenger is a child.
The International Air Transport Association and Uzbekistan Airlines did not immediately respond for comment.
