Anyone who's ever had to pack up a band's gear into a van can appreciate that you don't just throw it all in willy-nilly. It takes some planning, and maybe a little experience playing Tetris.
(Once while touring in Germany, I had a dream that our van was spinning around. It got me thinking about what would happen in a crash, and I realized we'd likely be killed by our own equipment. So next morning, to my bandmates' chagrin, I had the van unloaded and re-loaded in such a way as to be safer in an accident. Incredibly, the very next night, we hit a patch of ice on the autobahn, spun out, flipped over a guardrail and slid 50 feet on our side. The side doors flew open but nobody was crushed under a Marshal nor impaled by flying mic stands.)
So imagine deciding to take a stadium-size act on tour, packing everything - stage props, PA, lights, the works - on an airplane. Iron Maiden did that in a customized 757, playing gigs literally around the world in 66 days. This documentary talks about the logistics, especially the plane, which I found fascinating.
If you've ever flown to the smaller destinations in Alaska, you've likely been on a so-called "combi", usually a 737 or smaller plane configured for half cargo, half passenger space. None of these have first-class seats, though. Nor giant zombies on the tail.
Oh, and imagine your singer insists on donning a captain's uniform and playing co-pilot.
