As U.S. airlines are forced to cancel long-distance international routes, domestic spokes lose traffic, and at some point a flight becomes unprofitable and gets canceled.
The hub-and-spoke route systems, frequency of service and price competition are fiendishly complex and hard to compare with other industries.
The reasons lie in the economics of the hub-and-spoke route systems operated by American and other large carriers, according to Dale Morris, a spokesman for the airline.
More than two decades ago, deregulation sparked a similar wave of low-cost competition, but the big carriers fought back with their hub-and-spoke route systems and domination of major airports, and prevailed.
The airline will shift away from the hub-and-spoke route system it has used for a decade, which blankets the eastern half of the country with flights meant to carry passengers to and from connections at its hub airports.
With deregulation, many airlines consolidated operations geographically and adopted hub-and-spoke route systems in which travelers often pass through a carrier's hub airport to board a connecting flight.
And for large, modern passenger planes to stay full, they must travel hub-and-spoke routes, forcing passengers to go through Denver or Dallas when they want to get to Albuquerque.
They keep their costs lower than the legacies by hiring less experienced employees without pensions, flying point-to-point instead of inefficient hub-and-spoke routes, and using one or two jet models so they don't have to train pilots and mechanics on a dozen different varieties of planes.
A combination of traditional destination oriented routes along with direction oriented routes, which is called as Hub and Spoke network could be better for operating bus transit in large network.
Most analysts do not expect airlines to abandon their hub-and-spoke systems, which allow them to route passengers from smaller cities through a few big airports.
