I flew to Hood last week, I have a ski bag that has no padding what so ever. I just put some bubble wrap on them, 2 layers on the tips and tails, 4 around the bindings. I also wrapped a towel around them on the way there. They got there and back in perfect condition. I did a shitty job of wrapping them up again for the ride back and didn't even put towels around them and they were still perfectly fine. Don't worry too much about them.
Just remember to carry on your boots, good luck!
