Question: 3. Explain Why The “hub And Spoke” System Is Used In Aviation?

What is a hub and spoke network and why do some airlines use it while others do not?

The Hub-and-Spoke model is often used by airlines because it is efficient, flights are cheap, and it allows for easy expansion. However, this method also has its downfalls. First, facility costs are high. Goodwin and Cook estimate that up to 60% of flights only pass through hubs to make outbound connections.

What are two main benefits of the airline hub and spoke system?

The most immediate benefit of hub and spoke networks is to increase greatly the number of city pair markets that an airline can serve for a given volume of output. Consolidating many different traffic flows together through a hub can thus offer a very efficient means of relating supply to demand.
