Airlines have two methods of scheduling flights: Hub and Spoke and Point to Point. With the Hub and Spoke model, airlines route all make regional “hubs” that channel all of the local trafic and route customers to their destination. With the Point to Point model, as the name would suggest, flights go from point to point. Not all cities are connected, but in general, a city will have flights to every city in its region and would not not have any predetermined route if it needed to make a stop. Both methods have their strengths and weeknesses.
Suppose we have this space with 13 points:
Here is how we would connect them with hubs and spokes: (A,B, and C are the hubs)
The benefits of this model are:
• The majority of the flights go between A, B, and C. If someone doesn’t show up for one of those flights, there will certainly be someone in line to take their seat.
• With the multiple flights between hubs, the airline will be able to overbook these routes.
• The airline will not have to offer low traffic routes, like K==>L, which may not fill up.
The weeknesses are:
• The airline will not be competetive on many routes. Competitors will offer non-stop flights on many routes where hub-and-spoke method can only offer flights with stops.
• If there is a weather complication or mechanical slowdown at a hub, the entire airline has to readjust
• Because few people will stay on the same plane, the airline will have to move their bags to a different plane.
Here is how we would connect them with Point to Point:
The benefits of this model are:
• With a larger relative amount of non-stop flights, the airline will be able to pay less for docking, fuel, and baggage transfer per customer.
• The airline be able to offer routes like K==>L.
• A weather or mechanical complication at any airport is unable to disrupt the entire airline
The weeknesses are:
• If there is a weather complication or mechanical slowdown anywhere in the space, the airline will be somewhat disrupted
• Because few people will stay on the same plane, the airline will have to move their bags to a different plane.
In the USA, Southwest is the only major carrier to use the Point to Point model. Different airlines have different marketing strategies, in large part, because of what method of delivery they use. Continental is an elite carrier. It has hubs in major cities, so it offers a relatively high amount of nonstop flights to people who live within driving distance of the major cities (generally richer people and generally more business travel.) Southwest is a discount carrier, in part because it connects relatively small cities with other small cities, a service that caters to a relatively poorer, less business-oriented clientelle. Southwest is also able to let “bags fly free” because it has a relatively high amount of nonstop flights and doesn’t have to worry about transfering the bags between planes. Here are two examples of how the strategies play out in real life. Displayed below are the flight schedules for ExpressJet, and Delta in America.
