Mapping the World’s Busiest Air Routes
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
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 | ๐ฐ๐ท | Jeju โ๏ธ Seoul | 79,460 | 7 |
#2 | ๐ฆ๐บ | Melbourne โ๏ธ Sydney | 54,102 | 4 |
#3 | ๐ฎ๐ณ | Mumbai โ๏ธ Delhi | 45,188 | 6 |
#4 | ๐ง๐ท | Sรฃo Paulo โ๏ธ Rio de Janeiro | 39,747 | 3 |
#5 | ๐ฏ๐ต | Fukuoka โ๏ธ Toyko | 39,406 | 4 |
#6 | ๐ป๐ณ | Hanoi โ๏ธ Ho Chi Minh City | 39,291 | 3 |
#7 | ๐ฏ๐ต | Hokkaido โ๏ธ Tokyo | 39,271 | 4 |
#8 | ๐ฎ๐ฉ | Jakarta โ๏ธ Surabaya City | 37,762 | 6 |
#9 | ๐บ๐ธ | Los Angeles โ๏ธ San Francisco | 35,365 | 5 |
#10 | ๐ธ๐ฆ | Jeddah โ๏ธ 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.
International Routes
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 | ๐ฒ๐พ๐ธ๐ฌ | Kuala Lumpur โ๏ธ Singapore | 30,187 | 8 |
#2 | ๐ญ๐ฐ๐น๐ผ | Hong Kong โ๏ธ Taipei | 28,447 | 5 |
#3 | ๐ฎ๐ฉ๐ธ๐ฌ | Jakarta โ๏ธ Singapore | 27,046 | 7 |
#4 | ๐ญ๐ฐ๐จ๐ณ | Hong Kong โ๏ธ Shanghai | 20,678 | 5 |
#5 | ๐ฎ๐ฉ๐ฒ๐พ | Jakarta โ๏ธ Kuala Lumpur | 19,741 | 8 |
#6 | ๐ฐ๐ท๐ฏ๐ต | Seoul โ๏ธ Osaka | 19,711 | 8 |
#7 | ๐บ๐ธ๐จ๐ฆ | New York (LGA) โ๏ธ Toronto | 17,038 | 3 |
#8 | ๐ญ๐ฐ๐ฐ๐ท | Hong Kong โ๏ธ Seoul | 15,770 | 9 |
#9 | ๐น๐ญ๐ธ๐ฌ | Bangkok โ๏ธ Singapore | 14,698 | 5 |
#10 | ๐ฆ๐ช๐ฐ๐ผ | Dubai โ๏ธ 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.
Countries
Charted: The Number of Democracies Globally
How many democracies does the world have? This visual shows the change since 1945 and the top nations becoming more (and less) democratic.

Charted: The Number of Democracies Globally
The end of World War II in 1945 was a turning point for democracies around the world.
Before this critical turning point in geopolitics, democracies made up only a small number of the world’s countries, both legally and in practice. However, over the course of the next six decades, the number of democratic nations would more than quadruple.
Interestingly, studies have found that this trend has recently reversed as of the 2010s, with democracies and non-democracies now in a deadlock.
In this visualization, Staffan Landin uses data from V-DEMโs Electoral Democratic Index (EDI) to highlight the changing face of global politics over the past two decades and the nations that contributed the most to this change.
The Methodology
V-DEM’s EDI attempts to measure democratic development in a comprehensive way, through the contributions of 3,700 experts from countries around the world.
Instead of relying on each nation’s legally recognized system of government, the EDI analyzes the level of electoral democracy in countries on a range of indicators, including:
- Free and fair elections
- Rule of law
- Alternative sources of information and association
- Freedom of expression
Countries are assigned a score on a scale from 0 to 1, with higher scores indicating a higher level of democracy. Each is also categorized into four types of functional government, from liberal and electoral democracies to electoral and closed autocracies.
Which Countries Have Declined the Most?
The EDI found that numerous countries around the world saw declines in democracy over the past two decades. Here are the 10 countries that saw the steepest decline in EDI score since 2010:
Country | Democracy Index (2010) | Democracy Index (2022) | Points Lost |
---|---|---|---|
๐ญ๐บ Hungary | 0.80 | 0.46 | -34 |
๐ต๐ฑ Poland | 0.89 | 0.59 | -30 |
๐ท๐ธ Serbia | 0.61 | 0.34 | -27 |
๐น๐ท Turkey | 0.55 | 0.28 | -27 |
๐ฎ๐ณ India | 0.71 | 0.44 | -27 |
๐ฒ๐ฑ Mali | 0.51 | 0.25 | -26 |
๐น๐ญ Thailand | 0.44 | 0.20 | -24 |
๐ฆ๐ซ Afghanistan | 0.38 | 0.16 | -22 |
๐ง๐ท Brazil | 0.88 | 0.66 | -22 |
๐ง๐ฏ Benin | 0.64 | 0.42 | -22 |
Central and Eastern Europe was home to three of the countries seeing the largest declines in democracy. Hungary, Poland, and Serbia lead the table, with Hungary and Serbia in particular dropping below scores of 0.5.
Some of the world’s largest countries by population also decreased significantly, including India and Brazil. Across most of the top 10, the “freedom of expression” indicator was hit particularly hard, with notable increases in media censorship to be found in Afghanistan and Brazil.
Countries Becoming More Democratic
Here are the 10 countries that saw the largest increase in EDI score since 2010:
Country | Democracy Index (2010) | Democracy Index (2022) | Points Gained |
---|---|---|---|
๐ฆ๐ฒ Armenia | 0.34 | 0.74 | +40 |
๐ซ๐ฏ Fiji | 0.14 | 0.40 | +26 |
๐ฌ๐ฒ The Gambia | 0.25 | 0.50 | +25 |
๐ธ๐จ Seychelles | 0.45 | 0.67 | +22 |
๐ฒ๐ฌ Madagascar | 0.28 | 0.48 | +20 |
๐น๐ณ Tunisia | 0.40 | 0.56 | +16 |
๐ฑ๐ฐ Sri Lanka | 0.42 | 0.57 | +15 |
๐ฌ๐ผ Guinea-Bissau | 0.41 | 0.56 | +15 |
๐ฒ๐ฉ Moldova | 0.59 | 0.74 | +15 |
๐ณ๐ต Nepal | 0.46 | 0.59 | +13 |
Armenia, Fiji, and Seychelles saw significant improvement in the autonomy of their electoral management bodies in the last 10 years. Partially as a result, both Armenia and Seychelles have seen their scores rise above 0.5.
The Gambia also saw great improvement across many election indicators, including the quality of voter registries, vote buying, and election violence. It was one of five African countries to make the top 10 most improved democracies.
With the total number of democracies and non-democracies almost tied over the past four years, it is hard to predict the political atmosphere in the future.
