I was thinking about the average weight companies use for passenger plus hand luggage, 75kg. Is that correct?
That may well be for some budget companies but I have heard as 411 mentioned, the screams on the scales.
10kgs of hand baggage that leaves 65kgs for the pax, my wife would just scrape in so there is no hope for me..
My company uses 100kg as their base figure, and doing my maths on a A330 as an example, that turned out very close to the actual departure weight.
The difference is probably all the unaccounted carry on bags and duty free....
