***** To join INSNA, visit http://www.insna.org ***** I'm looking for data on international airline route networks between major cities (this is for a project one of my students is working on). Does anyone know of resources that could help construct this? ideally, I'd want to construct the graph with cities as nodes and weighted edges, where the weight represents the number of flights or some measure of the volume of travel between the cities. any pointers would be appreciated. thanks! -- Arun Sundararajan Associate Professor and NEC Faculty Fellow Director, IS Doctoral Program twitter/beta: @digitalarun http://www.stern.nyu.edu/faculty/bio/arun-sundararajan "Be the change you want to see in the world."
