This infographic presents T2RL's 10th edition of its global passenger volumes analysis. The report analyses full-year traffic data for 2025 and compares growth trends with previous years. The new format seeks to highlight these trends in a more impactful way. The 9th edition was published in June 2025.

One of the most significant developments in 2025 compared with previous years was the achievement of a new industry milestone: 5 billion passengers boarded. The data also suggests that the industry has entered a period of stabilisation following a volatile post-pandemic recovery, largely driven by tourism, leisure travel, and continued industry expansion.

As this report is based on 2025 traffic figures, it does not reflect the subsequent escalation of military conflict in the Middle East and its knock-on effects on fuel prices and demand. These developments are expected to create additional pressure on airlines through both higher operating costs and weaker consumer demand.

While modest growth across most regions largely defined 2025, notable outliers emerged in the data. South Korea surged ahead of its peers, while the United States was the only major market to experience a decline in passengers boarded.

Concentration remains high, with the top 50 airlines accounting for 58% of passenger volumes.
