The main outliers globally are of course the major US airlines which have no limit apart from AA at 23kg.

So really, if you want to guarantee to carry heavy hand baggage on every flight, you've got to stick with the US3 or BA. I suspect FlyWorld is much more used to those carriers rather than others around the world - or has been lucky so far (as are most of us on FT, I think!) that airlines don't strictly enforce their rules.
