The International Air Transport Association (IATA) has published the latest edition of its World Air Transport Statistics (WATS) report, which contains final data on global civil aviation for 2025.
Aviation Market Dynamics
According to the study, Central Asian countries demonstrated one of the most active rates of development in the aviation sector globally. By the end of the year, Uzbekistan served 12.5 million passengers, an increase of 16.9% compared to the previous year. Neighboring Kazakhstan showed even more impressive dynamics, increasing passenger traffic by 40% to 18.1 million people.
In addition to the region, high growth was recorded in Vietnam, where 80.9 million passengers were transported, a 14.8% increase. For comparison, the largest global aviation market, the United States, showed the weakest dynamics among the top 10 countries, increasing by only 1.6% with a total of 890.1 million passengers.
Top 10 Global Markets
China took second place with 776.1 million passengers, experiencing a growth of 4.8%. This is followed by the United Kingdom with 269.7 million, Spain with 252.7 million, and Japan with 223.5 million. Turkey ranked tenth in this group with 129.3 million passengers.
Premium Segment and Routes
The annually updated WATS report covers metrics on demand, capacity, and operational efficiency across the industry. The calculations are based on data from 1315 airlines, with over 250 international carriers providing specialized reporting to IATA.
A separate section is dedicated to premium travel. In 2025, business and first-class passengers used 109.7 million seats on international routes, which is 4.5% more than the previous year. This figure accounts for 5.5% of all international travelers. The sharpest growth in the premium segment was noted in Latin America, which saw an increase of 22.1%, while Europe remains the largest market with 39.7 million passengers.
Air Routes and Fleet
The route between Seoul (Gimpo) and Jeju in South Korea once again became the busiest in the world, transporting 13.3 million people in a year. Nine out of the ten busiest airport pairs are located in the Asia-Pacific region, and all of them are domestic flights. The only exception to the Asian dominance was the line from Jeddah to Riyadh, served by Saudi Arabia.
In the aircraft fleet segment, narrow-body jets lead. The Boeing 737 family conducted 10.8 million flights, a 12% increase compared to 2024, while the Airbus A320 performed 8.7 million flights, and the A321 performed 4.2 million flights. Among wide-body aircraft, the Boeing 787 and Airbus A350 are expanding their presence the fastest, increasing the number of flights by 40.8% and 117.4% respectively compared to 2019. Conversely, operations of the A380 giant decreased by almost a quarter.
