Point-to-point (top) vs hub-and-spoke (bottom) networks. The hub-and-spoke model, as compared to the point-to-point model, requires fewer routes. For a network of n nodes, only n − 1 routes are necessary to connect all nodes so the upper bound is n − 1, and the complexity is O(n).
Point-to-point (top) vs hub-and-spoke (bottom) networks. Point-to-point transit is a transportation system in which a plane, bus, or train travels directly to a destination, rather than going through a central hub. This differs from the spoke-hub distribution paradigm in which the transportation goes to a central location where passengers ...
An airline hub or hub airport is an airport used by one or more airlines to concentrate passenger traffic and flight operations. Hubs serve as transfer (or stop-over) points to help get passengers to their final destination. [a] [b] It is part of the hub-and-spoke system. An airline may operate flights from several non-hub (spoke) cities to the ...
The spoke-and-hub model, used by carriers such as American [5] and Delta, [6] relies on scheduling flights to and from hub airports. The hub-and-spoke model allows airlines to connect more destinations and provide more frequent routes, while the point-to-point system allows airlines to avoid layovers and have more cost effective operations.

In the immediate aftermath of deregulation, many large airlines adopted a hub-and-spoke system. In this system, several smaller routes ("spokes") are connected to a single larger route ("hubs") are selected an airport, the hub, as the point for flights from a number of origination cities, the spokes.
Example of a hub-and-spoke airline network. In most modern airline networks, outstations function as the 'spokes' of a hub-and-spoke structure. [4] Passengers departing from these remote locations—all having a wide array of final destinations—can be consolidated on inbound flights to an airline's hub.
Southwest does not use the "hub and spoke" system of other major airlines, preferring instead the "point-to-point" system with focus cities. [3] It has large operations in certain airports. An average of 80 percent of Southwest passengers are local passengers—only 20 percent are connecting passengers, a lower percentage than on most major ...
