The World’s Busiest Country Pairs By Seats This Month

by Staff


  • The busiest markets in terms of seats are between the UAE and India, Japan and South Korea, Spain and the United Kingdom, Canada and the United States, and Mexico and the United States in ascending order.
  • Japan to South Korea has experienced the most significant boom in air travel, with a 45.2% increase in seats offered compared to December 2019.
  • The Mexico to the United States route remains the busiest, with a 35.5% increase in seats offered compared to December 2019.

December is one of the busiest months for air travel of the year. Christmas tends to mark the end-of-year holidays with people traveling for various reasons.

As such, looking at the number of passengers traveling between country pairs is interesting. OAG has analyzed this data in its Airline Frequency and Capacity Trend Statistics Report with the top 5 results for the busiest country pairs for December 2023.

Operations between India and the United Arab Emirates have multiplied. This is unsurprising given the significant number of Indians in the United Arab Emirates, standing at about 3.3 million, representing roughly 40% of the population. Since diplomatic relations were established in 1972, India has become a vital economic partner for the United Arab Emirates and vice versa.

The route connecting Dubai to Mumbai is the fourth-busiest international air connection for the Middle East, with 241,122 seats on offer for December 2023. Low-cost airlines that offer this flight include SpiceJet, flydubai, and IndiGo, while the full-service carriers that operate the service are Air India, Emirates, and Vistara. Dubai to Delhi is equally a bustling route, coming in as the 7th busiest international air route from the Middle East with 207,884 seats.

High demand on the India-UAE sector is nothing new. Earlier this year, Simple Flying reported that summer seats from Abu Dhabi to the country were up by more than 20% in comparison to 2019 across six different airlines and 15 cities in India.

4 Japan to South Korea

2,247,914 seats

Since Japan eased its travel restrictions by the end of 2022, services between Japan and South Korea have skyrocketed. The route has even surpassed the seats on offer on the busy Jeju to Seoul route that regularly tops the leaderboard for being one of the busiest air routes in the world – even as a domestic flight.

The significant difference between 2019 and 2023 numbers is worth noting, representing a 45.2% increase. This is due to political tensions between the two countries in the last few years that have since died down. Japan has become a “boycott target among South Koreans unhappy with Tokyo’s actions on semiconductor materials exports,” as per Nikkei Asia.

Seoul Incheon to Tokyo Narita, Osaka Kansai, and Fukuoka are all featured in the Asia-Pacific region’s top 10 busiest international connections. The route to Tokyo comes in second place with 433,406 seats, Osaka in fourth place with 415,396 seats, and Fukuoka in 9th place with 295,972 seats on offer.

Simple Flying reported last December that the Mexico-US market achieved the top spot for several reasons, not least tourism, which remains a key factor. Other reasons included the migration of US workers who have made a life for themselves in cities in Mexico.

The busiest routes between the US and Mexico by number of operations per week this month include Guadalajara (GDL) to Los Angeles (LAX), Houston (IAH) to Mexico City (MEX), and Cancun (CUN) to Dallas (DFW) according to Cirium data.
