Tragedy of the Airport: Why you get stuck for hours at O'Hare :: Slate

Bottomline: If it was the tragedy of the commons that was the major cause of overscheduling, then we should see less of a problem at airports with a dominant carrier. But we don't; examination of the data says the opposite. Why? The hub and spoke business model of major airlines leads to domination of airports by one carrier or another; and in hub and spoke you want flights bunched so passengers are attracted by short layovers.
