When I emigrated from the UK on CX I was allowed 20kg of hold luggage, 7 or 10kg of hand luggage and a laptop bag.
My case weighed some 30kg, I got chatty with the check-in lady letting her know that I was industry staff so that got thru, they never weighed my hand baggage whilst they never specified how many laptops were allowed in one laptop bag ... I had 2 laptops in mine, they weighed a bl00dy ton
