• Total US scheduled seat capacity in August 2026 is 121.2 million seats, down 0.5% vs August 2025.
• Domestic capacity increased by 0.6% to 91.7 million seats.
• International capacity contracted by 3.6% to 29.5 million seats.
• American Airlines remains the largest carrier in the US with 22.4m seats.

The decline in seat capacity may indicate a shift in airline strategies, with some carriers focusing on efficiency and profitability over growth. The increase in domestic capacity suggests a strong demand for domestic travel, which could benefit airlines with a larger domestic presence. The contraction in international capacity may signal a decrease in global travel demand, which could impact airlines with a significant international presence.
