According to John Steele, vice president of research and operations at Co-operative Logistics Network (CLN), a company that offers services to freight forwarders, freight brokers, and carriers globally, "the conventional aviation network worldwide is very slow." These larger operators mostly engage in hub-and-spoke operations. There are a few flight hubs at nearly every airport in the world.We need a really flexible system in the air. The freight network needs the network as a pilot to take advantage of aircraft's ability to fly in a corridor and establish routes worldwide to take advantage of land transport.
