While these routes continue to recover, many remain below their 2019 capacity levels. The dominance of Asia-Pacific routes underscores the region's role as a critical driver of international air travel demand, supported by strong business and tourism connections.

Global Aviation Recovery

These rankings reflect the uneven recovery of international aviation. While demand for travel has rebounded significantly in many regions, challenges such as fluctuating demand, geopolitical factors, and operational constraints continue to influence seat capacity. The return of high-traffic routes like Hong Kong-Taipei to the top highlights a positive trend, but full recovery to pre-pandemic levels remains a work in progress.
