American, United prepare further capacity trims as fuel shock reshapes flying
American Airlines (AAL) and United Airlines (UAL) may cut capacity if fuel prices stay high. Both carriers report strong demand but face higher costs. AAL expects Q3 revenue to rise 16-19% YoY, with durable gains. UAL is already canceling some December flights and may adjust further in Q1 2024 and 2027. Both aim to protect profits by trimming less-profitable routes.

Background
Fuel price surge linked to geopolitical tensions has forced major U.S. airlines to reassess cost structures and capacity.

Likely modest downside as market prices in the cost shock.
New guidance on fuel impact and flight cancellations is material and not previously reported.
