Finland’s national carrier Finnair is asking passengers to be weighed voluntarily and anonymously so that it can update their standard weight figures
Actually a good idea! There was a regional plane crash circa 2000 because of (among many things) that
Instead of standard weight figures, I really don’t understand why airlines don’t just weigh passengers themselves. Have a scale right where the attendant scans your boarding pass. You’d get an exact value for the weight of the passengers and their carry-on luggage.
… and then what? People have already bought tickets
Then, if the overall weight of the aircraft is too high, offload some luggage and cargo.
So 20% of your passengers get to their destination without their suitcases, which will arrive … when the next under-loaded plane is available. Would you fly with them?
