With a trip to Greece pending I am thinking of ways to protect my backpack while in the hold. I have never flown with just a backpack before. Perhaps foolishly I went for the cheapest ticket option which includes a 10kg hold bag, which will be my liteskin atompack. I want to keep the weight to a minimum but want to give it some kind of protection and keep the straps from getting snagged in the conveyors. My only thoughts so far... Pipe lagging round my poles. Modifying an RWB or IKEA dimpla bag by cutting and re-sewing to size. Some egg crate type foam between bag and pack. Any other hints? Perhaps I should just wrap it in cling film and hope for the best. RWB bag, popular in China and Russia as luggage.
