Get a flight case, be prepared to pay a huge excess. In Australia its $10 per kilo over 20kg domestic and 30kg international. Depending on where you're going that gives you 10kg for pedalboard, 10kg for a guitar & then your amp if you take your personal stuff as carry on. My rig weighs about 60kg so thats about $600 excess domestic and really not worth it at all. FWIW me and the other guitarist in my band put our axefx's in a lightweight rack case and slave them into backline, even doing that we end up paying a little excess.
