Airports are the center for air travel as they are where passenger aircraft and cargo aircraft take off and land.
Airports help businesses connect and people move. In many instances, airports are essential as they are the fastest and most economical way for people to move from one place to another. Whereas it would take around a week via ship for voyages from New York to England, for instance, the average trip from New York City to London only takes around 7 hours via airplane.
Big airports can mean big business for many cities as they can facilitate economic activity such as increasing demand for hotels, taxis, and restaurants.
According to the 2021 Airport Traffic Report by the Port Authority of NY & NJ, New York City's biggest airport, JFK airport, plays a substantial role in the regional economy of New York City. In addition to employing 34,850 people directly, JFK airport contributes $42 billion in economic activity to the New York New Jersey Metropolitan area and supports around 195,000 total jobs. According to the same report, the Newark Liberty International Airport generates annual economic activity of $29.3 billion and supports 128,000 jobs.
The World's Biggest Airports
Some of the biggest airports are gigantic.
In 2019 before the pandemic, JFK airport served 62.55 million passengers including 34.3 million international passengers. In 2021, JFK airport served 30.7 million passengers as air travel began recovering.
Given it has the largest economy in the world, the USA has many of the world's biggest airports including the biggest overall. Given its large population and second largest economy, China has several of the world's biggest airports.
Companies That Own Airports
Since building big airports cost a lot of capital, many airports have been built or subsidized by governments. Given that private companies can sometimes realize more efficiencies than governments, some airports that were intially built by governments have since been privatized.
As a result, companies such as Heathrow Airport Holdings Limited owns and operates the UK's biggest airport, Heathrow Airport, and companies like Auckland International Airport Limited (ASX:AIA.AX) owns an airport in Auckland, New Zealand.
In terms of airport businesses, many private airport companies have not fully recovered from the pandemic in terms of their revenues given passenger traffic has not fully rebounded from the pandemic.
The Pandemic and Traffic Recovery
Many public airports have not seen passenger traffic fully recover from the pandemic. Nevertheless, current passenger traffic is higher than what it was in 2020, and many analysts believe passenger traffic will be even higher in one or two years.
According to the World Economic Forum data, overall passenger numbers in 2021 reached out 47% of 2019 levels with international passenger numbers amounting to 27% of the prepandemic levels. In 2022, the industry recovered further, with industry wide passenger numbers reaching 83% of 2019 levels. For the year, international passengers reached 69% of prepandemic levels and domestic air travel reached 93%.
While analysts expect air traffic to increase further, the future depends on consumer behavior, economic conditions, and the existing pandemic. If there is a worse than expected recession, for instance, the time to pre-pandemic levels could be longer than expected.
