Global air travel demand continued its upward trajectory in August 2025, with total traffic rising 4.6 percent compared to the same period in 2024, according to data released by the International Air Transport Association (IATA) on Wednesday. The monthly passenger load factor reached a record 86.0 percent, the highest ever recorded for August. Total capacity, measured in available seat kilometers (ASK), increased by 4.5 percent year-on-year. International traffic was the primary driver of growth, accounting for 87 percent of the net increase in global revenue passenger kilometers (RPK) during the month.

International RPK rose 6.6 percent compared to August 2024, with available capacity also up 6.5 percent. The international load factor rose slightly by 0.1 percentage point to 85.8 percent. Domestic markets recorded more modest gains, with RPK increasing 1.5 percent and capacity up 1.3 percent year-on-year. The domestic load factor stood at 86.3 percent, also a 0.1 percentage point improvement over the same month last year. The United States, the world’s largest domestic market, reported its eighth consecutive month of year-on-year declines in domestic load factor.
In contrast, Brazil posted strong domestic growth, supported by government measures aimed at boosting tourism. Asia-Pacific airlines recorded the highest regional growth, with a 9.8 percent increase in international RPK. Capacity in the region rose 9.5 percent, and the load factor reached 85.1 percent, up 0.2 percentage points from August 2024. Travel demand remained particularly strong in China and Japan, which posted growth of 11.8 percent and 12 percent, respectively.
Global airlines operate at record capacity during peak travel season
Middle East carriers registered an 8.2 percent year-on-year rise in international passenger demand, while capacity grew by 6.9 percent. The load factor improved by one percentage point to 83.9 percent. African airlines posted a 7.1 percent gain in demand and a 5.3 percent increase in capacity, lifting their load factor to 79.7 percent, up 1.3 percentage points from the prior year. Latin American carriers saw demand increase by 9.0 percent compared to August 2024, with capacity rising 9.3 percent.
The region’s load factor fell slightly by 0.2 percentage points to 84.7 percent. European carriers reported a 5.3 percent rise in demand, matched by a 5.3 percent increase in capacity, resulting in a steady load factor compared to a year ago. North American airlines posted the weakest growth among major regions, with international passenger demand increasing by 1.8 percent year-on-year. Capacity rose by 2.6 percent, while the load factor declined by 0.6 percentage points to 87.5 percent.
Europe maintains steady capacity and demand in August
This marked the fourth consecutive month of year-on-year declines in international load factor for North American carriers. Commenting on the data, IATA Director General Willie Walsh said that the August figures confirmed the 2025 peak northern summer travel season had set a new high, with aircraft operating at historically full levels. He noted that airlines are continuing to maximize efficiency amid ongoing challenges in aerospace supply chains and added that capacity was expected to grow by an additional 3.4 percent in October based on current airline schedules.
The data reflects continued resilience in global passenger markets despite ongoing macroeconomic and geopolitical uncertainties. August also marked a strong month for global air cargo, which rose 4.1 percent in demand year-on-year, supported by shifts in trade and logistical patterns. IATA represents some 320 airlines, accounting for 83 percent of global air traffic, and continues to monitor both passenger and cargo trends as the aviation sector adapts to evolving global conditions. – By Content Syndication Services.
