I'm sure there was a similar thread a ways back
1984 or thereabouts, Kunming to Rangoon (I figure I'm better off not posting the codes in this case), couple of Chinese generals in the front, me in the back.
Back in 2006 I flew Kandahar to Qatar in the back of a C-130. Other than the army captain I was traveling with, the back of the aircraft was completely empty. After takeoff, I wound up tossing my sleeping bag on the deck and sacking out for a few hours.
Given the length of the flight (USAF can't fly over Iran for obvious reasons), the flight crew was pretty good to us. We got microwaved pizza and access to their cooler of soft drinks.
