Solution for flying with back pain

I love traveling, but I hate dealing with back (and butt) pain that comes from cramped airline seats. This time I think I have a great solution! A friend introduced me to yoga rings, and they look like the perfect compact solution to massage sore spots on my back, butt, neck, and even calves while flying!Here are links to some yoga rings on Amazon:
