MIAMI – The International Air Transport Association (IATA) released data revealing how the COVID-19 crisis has affected international connectivity, shaking up the rankings of the world’s most connected cities.  

IATA’s air connectivity index measures how well connected a country’s cities are to other cities around the world, which is critical for trade, tourism, investment and other economic flows.

It is a composite measure reflecting the number of seats flown to the destinations served from a country’s major airports and the economic importance of those destinations.

London, the world’s number one most connected city in September 2019, has seen a 67% decline in connectivity. By September 2020, it had fallen to number eight.  

Shanghai is now the top ranked city for connectivity with the top four most connected cities all in China—Shanghai, Beijing, Guangzhou and Chengdu.  

New York (-66% fall in connectivity), Tokyo (-65%), Bangkok (-81%), Hong Kong (-81%) and Seoul (-69%) have all exited the top ten.

The study also reveals that cities with large numbers of domestic connections now dominate, showing the extent to which international connectivity has been shut down.

COVID-19 Impact on Connectivity by Region 

Africa suffered a 93% decline in connectivity. Ethiopia managed to buck the trend. During the first peak of the pandemic in April 2020, Ethiopia maintained connections with 88 international destinations. As for the rest of the continent, many aviation markets reliant on tourism, such as Egypt, South Africa and Morocco, were particularly severely impacted.  

Asia-Pacific saw a 76% decline in connectivity. Stronger domestic aviation markets, such as China, Japan, and South Korea performed better among the most connected countries in the region. Despite the relatively large domestic aviation market, Thailand was severely impacted perhaps due to the country’s high reliance on international tourism.

Europe experienced a 93% fall in connectivity. European countries saw significant declines across most markets, although Russian connectivity has held up better than Western European countries. 

Middle East countries saw connectivity decline by 88%. With the exception of Qatar, connectivity levels reduced by more than 85% for the five most connected countries in the region. Despite border closures, Qatar allowed passengers to transit between flights. It was also an important hub for air cargo. 

North American connectivity declined 73%. Canada’s connectivity (-85% decline) was hit more heavily than the United States (-72%). In part, this reflects the large domestic aviation market in the United States, which despite a significant passenger decline, has continued to support connectivity. 

Latin America suffered a 91% collapse in connectivity. Mexico and Chile performed relatively better than the other most connected countries, perhaps due to the timing of domestic lockdowns in these countries and how strictly they were enforced.

Statement from IATA

Sebastian Mikosz, IATA’s Senior Vice President for Member External Relations, said, “The dramatic shift in the connectivity rankings demonstrates the scale at which the world’s connectivity has been re-ordered over the last months. But the important point is that rankings did not shift because of any improvement in connectivity. That declined overall in all markets.”

“The rankings shifted because the scale of the decline was greater for some cities than others. There are no winners, just some players that suffered fewer injuries. In a short period of time we have undone a century of progress in bringing people together and connecting markets. The message we must take from this study is the urgent need to re-build the global air transport network.”

“The systematic testing of travelers is the immediate solution to rebuilding the connectivity that we have lost. The technology exists. The guidelines for implementation have been developed. Now we need to implement before the damage to the global air transport network becomes irreparable.”

Mikosz also said, “Governments must realize that there are major consequences for peoples’ lives and livelihoods. At least 46 million jobs supported by air transport are in peril. And the strength of the economic recovery from COVID-19 will be severely compromised without the support of a functioning air transport network.”
