Here's wot i do with my board & a unpadded Burton bag. Got a really large used cardboard box, like a box for a TV, cut it to the shape of my board, it wraps round my board so the edges are protected, had to use packaging tape to stick some bits together. On top of that i wrap my jacket & pants around the board & stick my gloves in the bag as well. Its only a single board bag but i still manage to get everything in there incl the bindings & boots. I cant remember how many times my boards been on a plane, at least 10 times & its never been damaged.
