'Basically i am asking if there's anything that you think airlines would be pleased to see on a CV , even non aviation related'
How about putting on the amount of equity your parents have in their house and your fathers credit card number. That should get you a place in the RHS at a few airlines!
Seriously, the thing i wished i had done at your age was to get down the local small airfield and offer my services cleaning aircraft helping refuel, washing cars for pilots etc. If you like aviation you will enjoy it and you will probably get a few free flights and make some good contacts for the future.
