Mapping the World’s Busiest Air Routes
Modern air travel gives us almost unlimited possibilities for getting around.
Whether you are acting on your wanderlust to explore new and exotic destinations, hopping to a familiar island for a well-deserved vacation, or jetsetting to London in the comfort of business class, the modern airline industry can get you almost anywhere you need to go.
But while flying allows us to have unique experiences, it’s often the case that we are all coming and going from many of the same popular destinations. As a result, the world’s busiest air routes have hundreds of flights per day connecting important city pairs together.
Ranking City Pairs
Today’s chart pulls data from OAG, which has compiled a detailed report ranking the busiest domestic and international air routes from around the globe.
It’s worth noting that the data is over the period of March 2018 to February 2019, and it excludes carriers that operate fewer than 500 routes per year.
Let’s dive in to see which city pairs have the most air travel between them.
Domestic routes are far more popular than international routes globally. According to the report, there are 15 domestic routes that have more operating flights per year than any international route anywhere.
Here’s a look at the top 10 domestic routes:
|Rank||Country||City Pair||Flights (Annually)||Carriers|
|#1||🇰🇷||Jeju ↔️ Seoul||79,460||7|
|#2||🇦🇺||Melbourne ↔️ Sydney||54,102||4|
|#3||🇮🇳||Mumbai ↔️ Delhi||45,188||6|
|#4||🇧🇷||São Paulo ↔️ Rio de Janeiro||39,747||3|
|#5||🇯🇵||Fukuoka ↔️ Toyko||39,406||4|
|#6||🇻🇳||Hanoi ↔️ Ho Chi Minh City||39,291||3|
|#7||🇯🇵||Hokkaido ↔️ Tokyo||39,271||4|
|#8||🇮🇩||Jakarta ↔️ Surabaya City||37,762||6|
|#9||🇺🇸||Los Angeles ↔️ San Francisco||35,365||5|
|#10||🇸🇦||Jeddah ↔️ Riyadh||35,149||5|
The busiest domestic route might be a surprise, unless you are familiar with Asian geography.
With almost 80,000 annual flights, the 300-mile hop between Seoul and Jeju Island in South Korea is the busiest air route in the world by a large margin. Overall, there are seven carriers competing on it each day, with over 200 daily flights available between them.
What makes Jeju so popular?
Known as the “Hawaii of South Korea”, this volcanic island is an extremely popular vacation destination within the country, and it hosts roughly 15 million guests per year.
On an international basis, the busiest route has almost 50,000 fewer flights per year than the Jeju-Seoul city pair listed above. Not surprisingly, this route – and many other top international routes – are also located in the Asia Pacific region.
|Rank||Countries||City Pair||Flights (Annually)||Carriers|
|#1||🇲🇾🇸🇬||Kuala Lumpur ↔️ Singapore||30,187||8|
|#2||🇭🇰🇹🇼||Hong Kong ↔️ Taipei||28,447||5|
|#3||🇮🇩🇸🇬||Jakarta ↔️ Singapore||27,046||7|
|#4||🇭🇰🇨🇳||Hong Kong ↔️ Shanghai||20,678||5|
|#5||🇮🇩🇲🇾||Jakarta ↔️ Kuala Lumpur||19,741||8|
|#6||🇰🇷🇯🇵||Seoul ↔️ Osaka||19,711||8|
|#7||🇺🇸🇨🇦||New York (LGA) ↔️ Toronto||17,038||3|
|#8||🇭🇰🇰🇷||Hong Kong ↔️ Seoul||15,770||9|
|#9||🇹🇭🇸🇬||Bangkok ↔️ Singapore||14,698||5|
|#10||🇦🇪🇰🇼||Dubai ↔️ Kuwait||14,581||4|
The short hop between Singapore and Kuala Lumpur takes only one hour, and it connects two major Southeast Asian commercial hubs. The route has 41 flights per day between eight airlines, making it one of the most competitive routes globally.
The busiest international route outside of the Asia Pacific is between Toronto and New York (LaGuardia) with 17,038 annual flights. Interestingly, it only has three competing carriers – the lowest of any of the top 10 routes.
Visualizing the Biggest Risks to the Global Economy in 2020
The Global Risk Report 2020 paints an unprecedented risk landscape for 2020—one dominated by climate change and other environmental concerns.
Top Risks in 2020: Dominated by Environmental Factors
Environmental concerns are a frequent talking point drawn upon by politicians and scientists alike, and for good reason. Irrespective of economic or social status, climate change has the potential to affect us all.
While public urgency surrounding climate action has been growing, it can be difficult to comprehend the potential extent of economic disruption that environmental risks pose.
Front and Center
Today’s chart uses data from the World Economic Forum’s annual Global Risks Report, which surveyed 800 leaders from business, government, and non-profits to showcase the most prominent economic risks the world faces.
According to the data in the report, here are the top five risks to the global economy, in terms of their likelihood and potential impact:
|Top Global Risks (by "Likelihood")||Top Global Risks (by "Impact")|
|#1||Extreme weather||#1||Climate action failure|
|#2||Climate action failure||#2||Weapons of mass destruction|
|#3||Natural disasters||#3||Biodiversity loss|
|#4||Biodiversity loss||#4||Extreme weather|
|#5||Humanmade environmental disasters||#5||Water crises|
With more emphasis being placed on environmental risks, how much do we need to worry?
According to the World Economic Forum, more than we can imagine. The report asserts that, among many other things, natural disasters are becoming more intense and more frequent.
While it can be difficult to extrapolate precisely how environmental risks could cascade into trouble for the global economy and financial system, here are some interesting examples of how they are already affecting institutional investors and the insurance industry.
The Stranded Assets Dilemma
If the world is to stick to its 2°C global warming threshold, as outlined in the Paris Agreement, a significant amount of oil, gas, and coal reserves would need to be left untouched. These assets would become “stranded”, forfeiting roughly $1-4 trillion from the world economy.
Growing awareness of this risk has led to a change in sentiment. Many institutional investors have become wary of their portfolio exposures, and in some cases, have begun divesting from the sector entirely.
The financial case for fossil fuel divestment is strong. Fossil fuel companies once led the economy and world stock markets. They now lag.
– Institute for Energy Economics and Financial Analysis
The last couple of years have been a game-changer for the industry’s future prospects. For example, 2018 was a milestone year in fossil fuel divestment:
- Nearly 1,000 institutional investors representing $6.24 trillion in assets have pledged to divest from fossil fuels, up from just $52 billion four years ago;
- Ireland became the first country to commit to fossil fuel divestment. At the time of announcement, its sovereign development fund had $10.4 billion in assets;
- New York City became the largest (but not the first) city to commit to fossil fuel divestment. Its pension funds, totaling $189 billion at the time of announcement, aim to divest over a 5-year period.
A Tough Road Ahead
In a recent survey, actuaries ranked climate change as their top risk for 2019, ahead of damages from cyberattacks, financial instability, and terrorism—drawing strong parallels with the results of this year’s Global Risk Report.
These growing concerns are well-founded. 2017 was the costliest year on record for natural disasters, with $344 billion in global economic losses. This daunting figure translated to a record year for insured losses, totalling $140 billion.
Although insured losses over 2019 have fallen back in line with the average over the past 10 years, Munich RE believes that long-term environmental effects are already being felt:
- Recent studies have shown that over the long term, the environmental conditions for bushfires in Australia have become more favorable;
- Despite a decrease in U.S. wildfire losses compared to previous years, there is a rising long-term trend for forest area burned in the U.S.;
- An increase in hailstorms, as a result of climate change, has been shown to contribute to growing losses across the globe.
The Ball Is In Our Court
It’s clear that the environmental issues we face are beginning to have a larger real impact. Despite growing awareness and preliminary actions such as fossil fuel divestment, the Global Risk Report stresses that there is much more work to be done to mitigate risks.
How companies and governments choose to respond over the next decade will be a focal point of many discussions to come.
The Sum of Its Parts: The Smartphone Multiplier Market
Every day, 3.3 billion people rely on their smartphones to stay connected. The products and services enabling this—the smartphone multiplier market—is now worth $459 billion.
The Sum of Its Parts: The Smartphone Multiplier Market
There’s a 60% chance you’re reading this article on a smartphone right now—a testament to how ubiquitous these devices have truly become in our lives.
We rely on smartphones every waking minute to stay connected. However, the various products and services—also known as the smartphone multiplier market—that allow us to use these devices in the first place can often be an afterthought.
Today’s chart uses data from Deloitte Insights to show just how sizable this ecosystem is becoming, and why it’s heating up as a battleground for big technology companies such as Apple, Alphabet, and Amazon.
The Smartphone Plateau
There are over 3.3 billion smartphone users in the world today.
The smartphone economy—estimated to pull in $944 billion in total revenue in 2020—is so massive that it rivals the GDP of countries like Indonesia and the Netherlands.
At the moment, the smartphones themselves contribute over half the market value. Despite the continued hype surrounding the release of new models, global unit shipments of smartphone devices appears to have reached a saturation point:
There are two theories as to why shipments are leveling off. First, product innovation is more iterative today than in the past, which means there are fewer groundbreaking features to entice consumers into purchasing new devices. A second factor is that people are simply holding onto their devices for longer than in the past.
As device sales plateau, tech giants are diversifying efforts to find new ways to lure customers back in—and another related market is growing more lucrative as a result.
What is a “Smartphone Multiplier”?
When people think of the smartphone market, hardware likely springs to mind first, but an equally important part of the equation is the plethora of apps, services, accessories, and complementary devices that help us connect with the digital world.
The ecosystem of these products and services are known as smartphone multipliers. According to Deloitte, this ecosystem will drive $459 billion of revenues in 2020, an impressive 15% increase from the prior year.
The market can be broken down into three main categories:
|Category||Market Value (2020e)||Sub-categories|
(68% of total)
|$176B: Mobile ads
(24% of total)
$9B: Smart speakers
(8% of total)
Largely driven by mobile advertising and app sales, content is by far the largest subcategory, accounting for 68% of revenues:
- Mobile advertising surpassed TV as the largest advertising channel in 2019, partially thanks to the relentless growth of online video and social media, making ads virtually unavoidable on a smartphone.
- Gaming apps are benefiting from the immense processing power of today’s smartphones—and will bring in over two-thirds of total app revenue in 2020. Apple’s app store brought in approximately $1.8 billion in sales between Christmas Eve and New Year’s Day alone.
If you’ve ever owned a pair of headphones or a powerbank, it’s easy to understand why accessories are the third-largest subcategory in the smartphone multiplier market. With more people ditching the cable for wireless headphones, this subcategory is also set to grow even more.
The Next $1T Economy?
In the U.S., 73% of adults go online several times a day or almost constantly, which makes it clear that they aren’t going to give up their smartphones anytime soon.
As a result, smartphone multipliers will continue to evolve and flourish, presenting a unique opportunity for investors and businesses.
Altogether, it’s expected that the smartphone multiplier market will grow between 5 and 10% annually through 2023, likely propelling the entire smartphone economy past the $1 trillion benchmark in the coming years.
