Top 10 Most Popular Asian-Pacific Routes

The Asia-Pacific region has seen tremendous growth in air traffic and passenger demand, and it's poised to keep growing.



February 11, 2023

DALLAS — It's been three years since the COVID-19 pandemic took hold of the world. Last year saw some recovery as governments uncurled their travel restrictions. Asia-Pacific regions were hit the hardest, as China was the epicenter of the outbreak. Despite this, Asia saw tremendous air traffic in 2022, and it is expected to grow this year.

Air travel is close to reaching pre-COVID-19 levels globally, with some regions already surpassing those levels and others expected to reach them in the next year or two. The Asia Pacific region is currently below pre-pandemic levels, but demand and capacity are increasing steadily and are expected to reach pre-pandemic levels by 2024-2025.

North American airlines were the first to become profitable after the pandemic, due to strong domestic demand in 2022. European and Middle Eastern airlines are expected to make some profits in 2023, while airlines in the Asia Pacific region are expected to turn a profit in the coming years, due to increased demand and optimized routes.

Let's take a closer look at the region and the most popular routes for its airlines. The data for this analysis were gathered from multiple sources, such as the OAG database, Cirium,, Flightaware, IATA, and ICAO datasets.

We should note that these route rankings may change from year to year, and we will do our best to keep them up to date with future posts.

APAC Outlook

The region is the most populated, with around 60% of the world's population residing in APAC countries. With the growth of developing countries in this region, demand soars higher and higher each year.

For over a decade, the APAC region has had the most rapid growth in the world. The global manufacturer of commercial airliners such as Airbus and Boeing expects more deliveries from the region.

The International Civil Aviation Organization (ICAO) and International Air Transport Association (IATA) have both pointed out the growth in the Asia-Pacific (APAC) region due to strong domestic demand and an increase in global connectivity. International organizations are working to boost growth in the region's air travel.

Despite this, some challenges must be addressed to ensure sustained growth in the APAC region. These include a lack of infrastructure, inconsistent regulations, and environmental pressures. Developing countries are addressing these issues by constructing new airports and increasing the capacity of existing airports. Regulatory bodies are also getting more involved in the operations of airlines, monitoring their activities closely.

Finally, airlines are shifting their focus to more environmentally friendly options such as Sustainable Aviation Fuel (SAF), in order to become carbon-neutral in the coming decades.

Airline choices over flying specific routes play a key role in the growth of regions. Asian and Oceania carriers are ticking the boxes right and doing exactly that, and APAC routes are leading in many aspects among other regions.

The Top spot is taken by the Hong Kong-Taipei route. The route is crucial for passenger and cargo operators due to its diverse trade establishments.

Hong Kong is a special administrative region of the People's Republic of China and is one of the most densely populated places in the world. It has two airports, but Chek Lap Kok International Airport (HKG) is the only one available for commercial operations in the city.

Taipei is the capital city and special municipality of Taiwan. Taipei is the economic, political, academic, and artistic center of Taiwan and one of the most prominent hubs in the East Asian region. Similar to HKG, Taipei has two airports; however, Taoyuan International Airport (TPE) is used for civilian travel.

Millions of passengers pass through the route on a regular basis. Due to high demand, numerous airlines fly on the route with their best fleets, and the majority of the time with widebody aircraft. The distance of 503 miles (810 km) between HKG and TPE airports is usually covered in two hours.

Among many carriers, China Airlines (CI), Cathay Pacific (CX), Hong Kong Airlines (HX), and EVA Air (BR) are the top operators on the HKG-TPE route. More than 1,000 flights per week use these routes.

These major carriers, along with other small regional airlines, fly various nonstop flights using heavy airliners. CI deploys its Airbus A330 fleet, CX operates its A330s and A350s, HX deploys the Boeing 787 Dreamliner and A320s, and lastly, BR deploys Boeing 787s and Airbus A320s over this route.

4. Bangkok-Hong Kong

At number four, we have the Bangkok-Hong Kong route. HGK has made the list of the most-flew routes twice.

Bangkok is the most populous city and the capital of Thailand. Its dense population necessitates two main airports, Don Mueang International Airport (DMK) and Suvarnabhumi International Airport (BKK), to serve the international travelers of the country.

Hong Kong, a more business-oriented region, is a major hub due to its strategic location, serving more passengers flights than Bangkok. The Bangkok-Hong Kong route is the third most popular route in the APAC region and is about 1048 mi/1688 km.

The route is served by around 900 flights a week operated by Thai Airways (TG), Cathay Pacific (CX), and Thai Smile (WE). Top carriers mostly fly the Airbus A350-900 to accommodate the strong demand for the route, with the flight typically taking two hours and 45 minutes.

The route from Manila to Singapore is the fifth most popular in the Asia-Pacific region.

Manila is the capital city of the Philippines and the second-most populous city in the country. The greater Manila region has four commercial airports, of which Manila International Airport (MNL) handles the maximum traffic in and out of the region. MNL is the primary gateway for visitors to the Philippines and serves as a hub for many international and domestic carriers.

Singapore, due to its advantageous location, serves as a destination for international travelers, offering connecting flights from the airport, similar to Dubai (DXB).

Mumbai is the most populous city in India and the eighth-most populous city in the world.

Tokyo is the capital and most populous city in Japan, as well as the most populous metropolitan area in the world. It has two airports serving its large population: Haneda International Airport (HND) and Narita International Airport (NRT).

Bottom Line

The APAC region is one of the fastest-growing in the world, and from this list, APAC routes have a strong presence.

Nine of the ten busiest global domestic routes belong to the APAC region. Six out of the ten busiest global international routes have seen APAC cities make the list. The countries of the Asia-Pacific region play an essential role in the global aviation industry and will remain a central part of it.

Furthermore, five of the ten most densely populated cities are located in the Asia-Pacific region. As a result, the list of the world's busiest airports includes APAC hubs. With the increasing growth and development in the region, we can expect a large number of passengers commuting on both domestic and international routes.

Stay tuned to Airways to see more high-traffic routes from other parts of the world such as Africa, Europe, Latin America, the Middle East, and North America.
