These styles of bike bag are basically just giant padded sleeves right? I fly a lot with bikes and wanted something similar that had the capability to pack down to a small size on the other end. So after a while I just decided to make my own, borrowing design idea's from the Orucase (check it out!) and savaged a hiking rucksack I found in a charity store for the back straps and zips etc. and an old sleeping pad for padding. It's done me about 10 flights now and come out the other end just fine. I would suggest approaching one of the small bikepacking bag manufacturers that are springing up everywhere and ask them to make you what you need, chances are it'll be cheaper than the likes of the freight baggage one which I think you'll have to get from the states? In the end making one myself probably cost me about £50 in terms of materials.
