With regard to baggage, airlines are their own worst enemies. Charging for checked in bags means passengers will go to almost any limit to avoid paying
I haven't had that problem PM.
When I emigrated from LHR with CX I was allowed a 20kg checked-in bag and some 7kg in the cabin, I was all over the place, my checked-in bag weighed some 26kg, my cabin bag some 10kg, "not a problem sir" came the words of the check-in lady who I had already become in to a banter with regarding if I required a visa for my destination country or not.
You get what you pay for!
