What You'll Learn
Strategic geographic location
A hub airport's strategic geographic location is key to its success. These airports are strategically positioned to serve as central points for connecting flights, with a wide range of routes for passengers to choose from. They are usually located in regions with high population density or where major airlines have a strong presence, allowing for convenient connections between various destinations, both domestic and international. For example, Emirates, Qatar Airways, Saudia, and Etihad Airways have established large hubs at their respective home airports, benefiting from their proximity to large population centres.
The geographic location of a hub airport is also important for the airlines themselves. Hubs allow airlines to funnel feeder flights with lower passenger volumes through strategically placed airports, without needing to use larger aircraft on less popular routes. This helps to reduce the number of empty seats, a significant cost for carriers. For instance, flights between smaller cities like Des Moines (DSM) and Dayton (DAY) can connect through a midway hub like Detroit (DTW) or Chicago (ORD), allowing airlines to better utilise their aircraft and reduce the risk of low passenger loads.
The location of a hub airport can also impact the development of other hubs. For example, the rapid growth of hubs at the home airports of Middle Eastern airlines has impacted traditional hubs such as London-Heathrow, Paris-Charles de Gaulle, and New York-JFK. These Middle Eastern hubs have become popular stopover points on trips between Europe and Asia, and their location has contributed to their popularity.
Additionally, the geographic location of a hub airport can influence its susceptibility to weather-related delays. For instance, DEN is an improvement over Stapleton in handling weather-related delays, but the location of Minneapolis-Saint Paul International Airport (MSP) means it experiences more days of bad weather.
Overall, the strategic geographic location of a hub airport is crucial for facilitating efficient connections for passengers and providing a central point for airlines to concentrate their operations.

Large size and high passenger volume
A hub airport is a central point for connecting flights, serving as a transfer point for passengers to reach their final destination. They are typically large airports that handle a significant volume of passenger traffic, often exceeding 40 million passengers annually.
Large hub airports with high passenger volumes are often located near large population centres, providing convenient connections for travellers. For example, the hubs of Emirates, Qatar Airways, Saudia, and Etihad Airways are located at their respective home airports, benefiting from their proximity to large cities. These hubs have become popular stopover points for travellers between Europe and Asia.
The size and passenger volume of a hub airport bring several advantages. Firstly, they attract more airlines and passengers, increasing competition and improving connectivity. This drives innovation and efficiency in the industry, benefiting both airlines and travellers. Secondly, larger hubs offer a wider range of flight options and frequencies, providing passengers with more choices and flexibility.
Additionally, large hub airports can facilitate banks of flights, where several flights arrive and depart within short periods, reducing connection times for passengers. However, this can also lead to congestion and delays if not managed properly.
Examples of large hub airports with high passenger volumes include Dubai International Airport, Schiphol Amsterdam Airport, and Hartsfield-Jackson Atlanta International Airport. These global hubs handle a significant number of international flights and passengers, solidifying their position as major connecting points.

Good design and infrastructure
Additionally, the infrastructure surrounding the airport plays a vital role. Adequate transport options, such as trains, buses, and roads, are essential to providing passengers with convenient access to and from the airport. This improves the overall travel experience and makes the hub airport more attractive to travellers.
The size of a hub airport is also a significant factor. These airports are typically larger, handling a substantial volume of passenger traffic, often exceeding 40 million passengers annually. Sufficient space is necessary to accommodate multiple concourses, runways, and aircraft parking spaces. For instance, Hartsfield-Jackson Atlanta International Airport (ATL) has doubled its runways and expanded its terminals to handle increased traffic efficiently.
Furthermore, the design and infrastructure of a hub airport should consider the surrounding population and demand. A hub airport should be strategically located in a region with a high population density or where major airlines have a strong presence. This enables airlines to maximise passenger numbers and attract travellers from a wider area. For example, Dubai International Airport (DXB) and Amsterdam Schiphol Airport (AMS) are well-positioned to serve as global hubs due to their proximity to large population centres.
Lastly, the infrastructure of a hub airport should support streamlined operations and cost efficiency. This includes efficient aircraft utilisation, such as consolidating feeder flights and reducing empty seats. Well-designed hub airports provide centralised work areas for ground operations and maintenance, facilitating timely mechanical fixes and aircraft adjustments. This, in turn, reduces operating costs and improves the overall efficiency of the hub.
