Income Statement Analysis: The Bottom-Line Duel
This income statement comparison reveals which airline operates with superior efficiency and profitability under current market conditions.
United Airlines Holdings, Inc. Analysis
United Airlines shows strong revenue growth, reaching $59B in 2025, with net income rising to $3.35B. Its gross margin stands at a favorable 64.1%, reflecting excellent cost control. Despite a slight EBIT decline, net margin growth and EPS improvements demonstrate operational momentum and improving profitability.
Southwest Airlines Co. Analysis
Southwest Airlines posts $28B revenue in 2025, with net income at $441M. Its gross margin is a neutral 17.4%, indicating tighter cost pressures. EBIT and net margin both declined year-over-year, signaling challenges in scaling profits despite modest revenue growth and a slight uptick in EPS.
High Margin Strength vs. Scale and Profit Challenges
United Airlines clearly outperforms Southwest with superior margins, larger absolute profits, and overall favorable income statement trends. Southwest’s narrower margins and declining net income suggest structural profitability issues. Investors prioritizing margin quality and profit growth will find United’s profile more compelling.

Efficiency & Valuation Duel: The Vital Signs
Financial ratios act as a company’s DNA, exposing hidden risks and operational strengths critical to investor decisions.
United Airlines Holdings, Inc.
United Airlines posts a robust 21.94% ROE and a solid net margin of 5.68%, signaling efficient profitability. Its P/E ratio of 10.91 suggests the stock trades at a reasonable valuation relative to earnings. Despite no dividends, United prioritizes reinvestment, supporting growth through capital allocation, though liquidity ratios raise caution.
Southwest Airlines Co.
Southwest Airlines reports a modest 5.53% ROE and a low net margin of 1.57%, indicating weaker profitability. The stock appears stretched with a high P/E of 50.61, reflecting elevated expectations. Southwest pays a 1.79% dividend, balancing shareholder returns with moderate operational efficiency but struggles on liquidity metrics.
Valuation Discipline vs. Profitability Edge
United Airlines offers superior profitability and a fair valuation, balancing risk and reward better than Southwest. Investors favoring operational strength and capital efficiency may prefer United, while those seeking dividends amid stretched valuations might consider Southwest’s profile.
Which one offers the Superior Shareholder Reward?
I compare United Airlines Holdings, Inc. (UAL) and Southwest Airlines Co. (LUV) on distribution philosophies and shareholder rewards. Neither pays dividends; LUV’s 1.8% yield in 2025 contrasts UAL’s zero payout. LUV’s dividend payout ratio near 90% signals reliance on dividends despite negative free cash flow. UAL avoids dividends, focusing on modest buybacks supported by positive free cash flow per share (~7.8). Both companies maintain share repurchases, but UAL’s free cash flow coverage and capital expenditure ratio (1.4x) are healthier. LUV’s higher leverage and volatile free cash flow challenge dividend sustainability. I conclude UAL offers a more sustainable total return profile in 2026 due to stronger free cash flow and prudent capital allocation.
Comparative Score Analysis: The Strategic Profile
The radar chart reveals the fundamental DNA and trade-offs of United Airlines Holdings, Inc. and Southwest Airlines Co., highlighting their financial strengths and weaknesses:
United Airlines dominates with high scores in discounted cash flow (5) and return on equity (5), reflecting strong profitability and valuation appeal. However, it carries a significant debt burden (score 1), a red flag in this capital-intensive sector. Southwest Airlines shows weaker performance across most metrics, with notably poor discounted cash flow (1) and valuation scores (1), signaling undervaluation risks but less financial efficiency. United Airlines presents a more balanced profile, while Southwest relies on modest debt levels but struggles with profitability and valuation.
Bankruptcy Risk: Solvency Showdown
United Airlines’ Altman Z-Score of 1.17 places it in the distress zone, while Southwest’s 2.37 sits in the grey zone, indicating a better buffer against bankruptcy risk in this cycle:
Financial Health: Quality of Operations
Southwest Airlines scores an impressive 8 on the Piotroski F-Score, signaling very strong financial health and operational quality. United Airlines’ 6 is average, suggesting some internal metrics warrant caution:

The Moat Duel: Analyzing Competitive Defensibility
A structural moat is the only barrier protecting long-term profits from relentless competitive erosion. Let’s explore how United Airlines and Southwest Airlines defend their turf:
United Airlines Holdings, Inc.: Global Network and Scale Advantage
United Airlines’ moat stems from its extensive international network and diversified global routes. This manifests in a strong gross margin of 64% and improving profitability metrics. Expanding in Asia and Latin America deepens its moat in 2026.
Southwest Airlines Co.: Low-Cost Operating Model
Southwest’s primary moat is its cost advantage through operational efficiency and a simplified fleet. However, its margin stability lags United’s, reflecting lower profitability and declining ROIC trends. Opportunities lie in digital platforms and ancillary services expansion.
Network Reach vs. Cost Efficiency: The Moat Showdown
United Airlines’ broader geographic footprint and rising ROIC create a deeper moat compared to Southwest’s shrinking profitability. I see United better positioned to defend market share amid intensifying competition globally.

Which company shows a better risk-adjusted profile?
UAL’s most impactful risk is its high leverage and liquidity constraints, raising concerns over financial flexibility. LUV’s primary risk lies in weak profitability and stretched valuation multiples, signaling operational and market challenges. Despite UAL’s financial strain, its superior ROE and discounted cash flow scores indicate better capital efficiency. LUV’s stronger Piotroski and Altman Z-scores suggest more stable fundamentals, but its valuation and profitability weaknesses temper enthusiasm. Overall, UAL presents a riskier balance sheet, but LUV’s operational challenges and high P/E ratio undermine its risk-adjusted appeal.
Final Verdict: Which stock to choose?
United Airlines (UAL) stands out for its growing profitability and improving return on invested capital, signaling a budding competitive edge. Its key strength lies in value creation through enhanced operational efficiency. A point of vigilance remains its stretched liquidity position, which could pressure flexibility. UAL suits investors targeting aggressive growth with a tolerance for balance sheet risks.
Southwest Airlines (LUV) offers a strategic moat rooted in a lower debt load and stronger interest coverage, providing a safer financial cushion. Its operational model emphasizes stability and capital discipline despite weaker profitability metrics. LUV fits portfolios that prioritize growth at a reasonable price, appealing to those seeking more stability over high returns.
If you prioritize capital efficiency and improving profitability with a willingness to accept liquidity risks, UAL is the compelling choice due to its upward ROIC trend and value creation. However, if you seek financial safety and steadier cash flow with less aggressive growth, LUV offers better stability thanks to its healthier leverage profile and stronger interest coverage. Each name addresses distinct investor profiles within the cyclical airline sector.
