I guess you got lucky with the carry-on, I wouldn't risk putting my zuca through with the rest of the baggage - probably get lost or stolen
At least you know who's handling it and are certain it's gonna be safe when you have it as carry-on
I try to keep my zuca as organised as possible but as it was not originally designed as a skate bag it's not so easy to keep in order.
I have my skates in the main compartment (my hoodie is folded up on the floorpiece, and i put my skates on top of that)
In the door bit I have a 2 halves of a car sponge (which I use as padding for my knees when I do jumps) and little kitchen sponges which I put in my socks to prevent blisters. I have a little first aid kit (bandaids, paracetamol, gel blister pads etc.) in the top pocket on the door and many pairs of nylon socks in the bottom pocket.
In the mesh 'shelf' thing at the top I keep a little towel, hairbrush, gloves (about 4 pairs
)
In one ouside pocket I keep my guards, a notebook/pen and a tea towel to dry skates
In the other outside pocket I keep deodorant, water bottle, snack, ipod
I keep my money in one of the really little pockets on the outside (it has about 3 plush keyrings hanging from it
)
I don't tend to keep anything in the outside mesh pockets as I travel to the rink on public transport i'm afraid stuff with fall out
I love not having to carry the zuca, my old skate bag gave me bad shoulder pain (I did stuff a lot of stuff into it
) the only bad thing is trying to get the zuca on and off buses and trains...bit of a hassle
Another thing, I thought the zuca wheels were meant to mean you could wheel your zuca around quietly...you can hear me miles away with mine it's so noisy on normal paths
