Geographic locations of the airports in China and USA. (a) Top 30 airports in China. (b) The FAA core 30 airports. Red markers are the airports in the rich clubs (i.e., the 15 airports in China and the 16 airports in USA), while squares are the airports that have been identified with higher betweenness centrality in the delay networks.
