Similar thing happened some years ago. When my friend resubmitted her case to be weighed I was sure she would not get away with it - but she did. Phew, but then I spent the flight worrying that the plane was overloaded…
Perhaps the airlines should weigh the passengers as well as the baggage.
Absolutely, and charging the largest extra for the amount they encroach into other passengers space.
On second thoughts, reducing the charge for a passenger who has to sit next to a fat mountain.
