Will American Airlines' Operating Margin Remain Under Pressure?

American Airlines (AAL) projects its adjusted operating margin to decline significantly in Q3 2025 to a range of -1% to +2%, despite an 8.2% margin in Q2. This anticipated pressure is attributed to subdued revenue growth (down 2% to up 1% year-over-year) and escalating operating costs, primarily driven by substantial labor expenses, including pilot wage hikes expected to increase over 8% in 2025. Consequently, AAL's profitability trails industry peers, and its shares have underperformed, though valuation metrics suggest it is currently undervalued.

Analysis

American Airlines (AAL) is facing significant operational headwinds, with management guiding for a sharp decline in adjusted operating margin to a range of negative 1% to positive 2% for Q3 2025. This projection marks a stark reversal from the 8.2% margin achieved in Q2 2025 and indicates severe pressure on profitability. The challenge is twofold: a stagnant revenue environment, with Q3 sales expected to be between down 2% and up 1% year-over-year, and escalating operating costs. Labor expenses are a primary driver of cost inflation, with salaries, wages, and benefits expected to increase by more than 8% in 2025 following a 9.9% rise in 2024. Consequently, AAL's cost per available seat mile is projected to increase by 2.5-4.5% in Q3. This performance lags significantly behind key competitors; Delta Air Lines (DAL) guides for a 9-11% Q3 operating margin, and Copa Holdings (CPA) maintains a robust margin outlook of 21-23% for full-year 2025. Despite its shares underperforming the industry by over 21 percentage points in the past six months, AAL trades at a low forward price-to-sales multiple of 0.15, well below the industry's 0.69. This valuation discount is juxtaposed with a recent upward revision in consensus EPS estimates for the upcoming quarters, creating a conflicting picture of deep operational challenges alongside potential deep value.

Key Decisions for Investors

• Investors should be cautious of the significant margin compression and negative forward guidance, which signal fundamental operating challenges ahead for American Airlines.
• While AAL appears undervalued on a price-to-sales basis, this may reflect a value trap given its pronounced underperformance and weaker profitability relative to peers like DAL and CPA.
• Consider the stark performance gap between AAL and more profitable airlines as a potential basis for a pairs trade, favoring competitors with stronger margin control and operational efficiency.
• Closely monitor labor negotiations and cost per available seat mile (CASM) in future earnings reports, as these are the critical metrics driving the company's current financial pressure.
