Delta Airlines Hubs: Guide to Delta’s Major Airport Terminals

Delta Airlines, headquartered in Atlanta Georgia, is the world’s 2nd largest airline, operating flights to 325+ destinations in 52 countries across six continents. It operates nine major U.S. hubs, with Atlanta Hartsfield-Jackson being the largest in terms of passenger volume and departures.

Delta was an early adopter of the hub-and-spoke model, which became the dominant way large airlines organize routes in the U.S.

The hub and spoke system revolutionized the way airlines schedule and operate their flights. Instead of having many point-to-point routes, airlines could now funnel flights through major hub airports. This provided airlines with better efficiency, increased connectivity, and streamlined operations. Passengers from smaller cities could now connect through a central hub to reach a wide range of destinations, and airlines could maximize their fleet utilization and reduce costs.

As part of its hub-and-spoke business model Delta operates out of nine hubs that are strategically located, connecting passengers to over 300 domestic and international destinations.

This article provides an overview of each of the Delta hubs, including a terminal map and passenger volume information.
