Excluding the Middle East, demand increased by 1.2%. Total capacity, measured in available seat kilometers (ASK), decreased -2.9% year-on-year. The load factor was 83.1% (-0.4 ppt compared to April 2025).

Also, international demand fell -5.3% compared to April 2025. Excluding Middle East, demand grew by 1.9%. Capacity was down -5.1% year-on-year, and the load factor was 83.9% (-0.2 ppt compared to April 2025).

Meanwhile, domestic demand was flat compared to April 2025. Capacity increased 0.8% year-on-year. The load factor was 81.9% (-0.7 ppt compared to April 2025).

“The 46.6% fall in demand for carriers in the Middle East due to war in the region was so acute that it dragged overall demand down -3.4%. The situation for air transport remains highly volatile. The cost of jet fuel more than doubled in April, which is pushing airfares up. Forward schedule data is showing a reduced offering in the coming months, indicating that airlines are balancing high fuel costs and weaker demand.” said Willie Walsh, IATA’s director general.

Regional Breakdown – International Passenger Markets 

International RPK fell -5.3%, with capacity falling -5.1%. However, this decline was caused by continuing heavy falls in demand for Middle East carriers. Excluding the Middle East, RPK increased by 1.9%. North America was flat and all other regions reported growth.

Asia-Pacific airlines achieved a 3.0% year-on-year increase in demand. Capacity increased 0.7% year-on-year, and the load factor was 87.5% (+1.9 ppt compared to April 2025), a record high for April. There was a notable slowdown in traffic on the Japan-China corridor, due to ongoing political tensions.

European carriers saw a 0.9% year-on-year increase in demand. Capacity increased 0.3% year-on-year, and the load factor was 84.9% (+0.6 ppt compared to April 2025). Direct traffic between Europe and Asia increased 15.3% as it replaced traffic transiting through the Middle East.

North American carriers saw a 0.0% year-on-year increase in demand. Capacity decreased -1.1% year-on-year, and the load factor was 83.9% (+0.9 ppt compared to April 2025).

Middle Eastern carriers saw a -48.1% year-on-year decrease in demand. Capacity fell -38.4% year-on-year, and the load factor was 70.1% (-13.1 ppt compared to April 2025). Traffic was impacted by the ongoing Iran war, though the decline slowed a little compared to March, as an uneasy ceasefire came into effect.

Latin American airlines achieved an 8.9% year-on-year increase in demand. Capacity climbed 7.2% year-on-year. The load factor was 84.6% (+1.4 ppt compared to April 2025).

African airlines saw a 2.2% year-on-year increase in demand. Capacity was up 1.2% year-on-year. The load factor was 77.9% (+0.7 ppt compared to April 2025).

Domestic Passenger Markets 

Domestic RPK was flat in April compared to April 2025. Growth in Brazil, China, and Japan was balanced out by falls in Australia, India, and the United States. Load factors fell in most of the major markets barring China and Japan, though it should be noted that capacity in the Japanese market has declined for eight months in a row.

The International Air Transport Association (IATA) released data for August 2025 global passenger demand with the following highlights:

•    Total capacity, measured in available seat kilometers (ASK), was up 4.5% year-on-year. The August load factor was 86.0% (+0.1 ppt compared to August 2024), a record high for the month.

•    International demand rose 6.6% compared to August 2024. Capacity was up 6.5% year-on-year, and the load factor was 85.8% (+0.1 ppt compared to August 2024).

•    Domestic demand increased 1.5% compared to August 2024. Capacity was up 1.3% year-on-year. The load factor was 86.3% (+0.1 ppt compared to August 2024).

“August year-on-year demand growth of 4.6% confirms that the 2025 peak northern summer travel season reached a new record high. Moreover, planes were operating with more seats filled than ever with a record load factor of 86%. Despite economic uncertainties and geopolitical tensions, the global growth trend shows no signs of abating, as October schedules are showing airlines planning 3.4% more capacity. Airlines are doing their best to meet travel demand by maximizing efficiency, making it even more critical for the aerospace manufacturing sector to sort out its supply chain challenges,” said Willie Walsh, IATA’s director general.

Air passenger market in detail – August 2025

Regional Breakdown – International Passenger Markets

International RPK growth reached 6.6% in August year-on-year, and load factor reached a historic high. International traffic was by far the dominant driver of growth, accounting for 87% of the net increase in global RPK in August.

Asia-Pacific airlines achieved a 9.8% year-on-year increase in demand. Capacity increased 9.5% year-on-year, and the load factor was 85.1% (+0.2 ppt compared to August 2024). Growth was driven by strong demand from China and Japan (+11.8% and +12% respectively).

European carriers had a 5.3% year-on-year increase in demand. Capacity increased 5.3% year-on-year, and the load factor was flat (0.0 ppt compared to August 2024).

North American carriers saw a 1.8% year-on-year increase in demand. Capacity increased 2.6% year-on-year, and the load factor was 87.5% (-0.6 ppt compared to August 2024). This was the fourth consecutive month of YoY declines in international PLF for North America.

Middle Eastern carriers saw an 8.2% year-on-year increase in demand. Capacity rose by 6.9% year-on-year, and the load factor was 83.9% (+1.0 ppt compared to August 2024).

Latin American airlines saw a 9.0% year-on-year increase in demand. Capacity climbed 9.3% year-on-year. The load factor was 84.7% (-0.2 ppt compared to August 2024).

African airlines saw a 7.1% year-on-year increase in demand. Capacity was up 5.3% year-on-year. The load factor was 79.7% (+1.3 ppt compared to August 2024).

Domestic Passenger Markets

Domestic RPK rose 1.5% over August 2024 and contributed only 13% of the global increase in August RPK, down from 25% a year ago.

US domestic load factor fell YoY for the eighth consecutive month. The sharp expansion in Brazil was helped by government efforts to promote tourism.
