Airline hub
Airline hubs are airports that an airline uses as a transfer point to get passengers to their intended destination. It is part of a hub and spoke model, as opposed to the Point to Point model, where travelers moving between airports not served by direct flights change planes en route to their destinations.[citation needed]
Many airlines also use focus cities, which have a good catchment area and function much the same as hubs, but on a smaller scale and may also function as feeders to main hubs. Some airlines also use the term secondary hubs for large focus cities.[1] Some airlines may use only a single hub, while other airlines use multiple hubs. Hubs are used for both passenger flights as well as cargo flights.[citation needed]
A hub in the middle of a route is more effective than at either end as connecting traffic more easily fills the plane - passengers prefer a one-stop (two-leg) route over a two-stop (three-leg) route.[2] The FAA uses the term airline hub based on number of commercial passengers in the FAA airport categories, re-evaluated every year. Airlines often have their headquarters in a major hub.
Competition
A dominant airline will take competitive measures to defend its preferred position at a hub airport.[3] This can stifle competition, for example Pro Air's battle with Northwest when it briefly flew out of Detroit City Airport: Northwest was able to out compete the short-lived discount carrier by matching its fares and offering more frequent flights.[4]
New entrants, such as Spirit Airlines at Detroit Metropolitan Wayne County Airport and Dallas-Fort Worth International Airport, or AirTran at Hartsfield-Jackson Atlanta International Airport, allege to have been the target of exclusionary practices by the dominant carrier, like in Cincinnati/Northern Kentucky International Airport or all Delta Air Lines hubs.
Airports where a single airline's share of flights is at or above 70 percent can be called fortress hub.[5] For example, in 2010 US Airways occupied 85 (plus 1 shared with Lufthansa) out of 97 total gates and accounted for approximately 90% of passenger traffic at Charlotte Douglas International Airport. The existence of fortress hubs makes possible the use of airline booking ploys such as "hidden city" ticketing.
