Yep when travelling you want to get as much padding around your board/s as you can, stand an watch the guys at the airport unpacking you boards and you will shudder. I remember standing on the tarmac in the maldives watching one guy up in the hold litterally pickup a board and throw it out of the hole, every second or third board went direct to the ground and most of them were damaged.
Fortunately I packed two boards in oversized double bag, individually bubble wrapped, no fins, towels, rashie whatever soft I could find around nose/ tail etc as described above and got away without a mark

everyone else on the boat used up my repair kit within about an hour

Go bigger you won't regret it.
