There's probably some labour cost hidden in other categories as well, like station costs and reservation costs. But still, I'd expect labour to rank much higher considering that 10:1 productivity advantage.
There's actually another thing that's surprising. Low cost airlines, at least in europe, have a younger fleet of aircraft using less fuel. That doesn't seem to figure in the chart either.
