Consider wheels.

A friend and I took a trip to the tropics with our rigs. He had his rEvo in one of those tidy bags shown here. My Meg was in a fabric carry on bag with a pull up handle. We had to change planes in an American airport. We had to que up for ever to have our bags inspected and standing around with his rig on his back was not the most comfortable experience my friend has endured. I was happy to be able just drag my bag around.
