I'm surprised you don't have a couple of flashlights with extra batteries in there. They are indispensable.
I carry a head mounted LED light (with white, red and green options) in the flight bag along with a couple 10,000 mAh batteries and a few charging cables. I also usually have a modern LED version of the old angle head flashlight in there as well. I guess I don't consider it to be specific to airplane camping, but rather just airplane use.
