I plan to fly Frontier Airlines from Ohio to Colorado next month, and I'm considering bringing my Phantom with me. I'm looking for advice and cautions. I'm willing to buy a decent hard case for it, but I don't want to spend an exorbitant sum on a paramilitary tactical case designed to withstand minor nuclear explosions; I just want something that will hold up to airline baggage handlers. I also want to know if there are any prohibitions I'm failing to find on the Frontier or TSA web sites. Any problems with the lithium batteries?
