Compared to the week of March 1, EU route capacity grew 18%, and the three major airlines and their subsidiaries collectively increased capacity by 21%, among which Air China grew 28%, China Southern grew 18%, and China Eastern grew 15%.
Analysis framework
The report employs a route capacity data tracking methodology, assessing aviation market recovery by comparing capacity changes across different time dimensions. Key analysis focuses on Week-over-Week and Year-over-Year changes, as well as comparisons to pre-pandemic levels, revealing recovery progress and demand shifts across routes from multiple perspectives.
Methodology notes
ASK Indicator in Airline Capacity Analysis
ASK (Available Seat Kilometers) is a core metric in the aviation industry for measuring capacity supply, reflecting the total transport capacity provided by airlines. This report analyzes capacity adjustment trends across routes using YoY and WoW changes in ASK.
Route Capacity and Demand Matching Analysis
The report infers supply-demand relationships through increases or decreases in capacity across routes. Capacity increases typically reflect recovering demand, while capacity reductions may indicate insufficient demand or adjustments in competitive strategy.

Impact & implications
Report data shows structural divergence in Chinese airlines' international capacity, with regional Asia-Pacific routes recovering better, while long-haul international routes, particularly the US, recovered more slowly. This divergence reflects differences in the recovery of tourism demand and business travel across regions, providing reference for airlines adjusting capacity deployment.
