- Classifying the types of networks has been a focus of analysis in the
recent, small-world research. A unifying theory has been introduced to
provide an integrative perspective on the statistical properties of a
variety of real-world networks. This theory postulates that the existence
of constraints deters the emergence of a scale-free network. For
example, the theory argues that the constraints of airport capacity limit
the growth of air traffic, blocking the emergence of a scale-free network.
We challenge this argument by reexamining the context of the airline
industry. We empirically show that the U. S. airline route network is a
scale-free network despite the presence of capacity constraints. We
propose a new avenue for future research.
