European airline carry on bag weight and dimension rules

I took this photo last week at London City Airport and am sharing it here so that others can have this information. Especially musicians looking to take instruments in the cabin rather than in the hold. I am not convinced that the British Airways figure is correct as 23Kg is their hold baggage allowance. In any case you are not going to be taking a trumpet case on any of these airlines as they will always be  too long.
