Few airlines rely so heavily on transcontinental hubs as United Airlines. All three of the US’s principal legacy carriers, including United Airlines, Delta Air Lines, and American Airlines, aim to connect travelers through their massive hubs in order to offer the most travel options. However, United Airlines is in an even more reliant position, with its hubs serving as critical linchpins in its global network. Specifically, United Airlines places a heavy emphasis on transcontinental connecting traffic, with the airline offering flights to many lower-demand destinations on both coasts and using its mid-continent hubs to funnel passengers to these cities.
