Commercial airlines operate with greater efficiency because they utilize a hub-and-spoke structure. They move a large number of passengers through a central location, and disburse the travel to other central operating locations. This allows timely management of customers and high throughput. It also maintains all maintenance, cleaning, catering, and customer services in a central location. As more passengers are moved through point A to all other access points, this allows more efficiency and easier management. By extension, generating more revenue for the airline which aids in keeping costs low for the passengers.
