For work I have found the best way to get confortable in the plane. I find that I can take off my helmet and place it on top of my reserve parachute and rest my head on that ballistic pillow and sleep until they give the 10 minute warning.....also since most of our jumps are at 3 AM I find it very easy to fall sleep. This plane ride equals sleep conditioning has transfered into my commercial fly experiences where as soon as the engines come one my head is tilted back and I am snoring.
