Yes I've noticed that Rimowa has become much more popular these days, looking at the HKG carousels. So I really wonder if CX is doing this network-wide.
Maybe it's a Menzies initiative as CX charges them for damaged luggage. So they are saying "Well on the Australia side we do everything we can to prevent damage, so don't blame us"?
I can't imagine any other carrier really caring about this, and even contemplating compensation for normal wear and tear.
