5 US Airports Where No Airline Has A 50% Market Share

In the United States, most airlines operate a hub-and-spoke system, which involves funneling passengers through large hub airports to efficiently offer connections to destinations across the country and to international cities. Naturally, this led to many airports being dominated by traffic from a single airline operating a hub there. As a result, the vast majority of US airports have one airline which accounts for more than 50% of passenger traffic.
