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

Total demand, measured in revenue passenger kilometers (RPK), was up 2.6% compared to June 2024. Total capacity, measured in available seat kilometers (ASK), was also up 3.4% year-on-year. The June load factor was 84.5% (-0.6 ppt compared to June 2024).

International demand rose 3.2% compared to June 2024. Capacity was up 4.2% year-on-year, and the load factor was 84.4% (-0.8 ppt compared to June 2024).

Domestic demand increased 1.6% compared to June 2024. Capacity was up 2.1% year-on-year. The load factor was 84.7% (-0.4 ppt compared to June 2024).

Regional Breakdown - International Markets

International RPK growth reached 3.2% in June year-on-year, but load factor fell across all regions as capacity growth outstripped demand. The steepest fall in RPK growth from May was in the Middle East, where international traffic contracted 0.4% year-on-year, impacted by military conflict. 

Domestic Markets

Domestic RPK rose 1.6% over June 2024 and load factor fell by 0.4 ppt to 84.7% on the back of a 2.1% capacity expansion. Brazil was the standout performer, and the US domestic market saw a very slight expansion for the first time in four months.
