AAL vs DAL: Which Is the Better Buy in 2026?
Last updated August 2026
Short answer
AAL and DAL are similarly sized, but AAL trades noticeably cheaper on forward earnings (6.08x vs 9.87x): the market is paying up for DAL's profile and pricing AAL more conservatively, or for faster growth. Which you prefer comes down to the drivers you believe, and whether adding either over-concentrates what you already own.
AAL vs DAL: the tie-breaker metrics
Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | AAL | DAL | What it tells you |
|---|---|---|---|
| Forward P/E | 6.08 | 9.87 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Beta | 1.32 | 1.29 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 60% of range | 81% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
Reading it: AAL is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.
Before you buy: how AAL and DAL affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. AAL and DAL share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined AAL and DAL exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does American Airlines Group (AAL) do?
American Airlines Group operates the world's largest airline by scheduled passengers and fleet size, flying a hub-and-spoke network centered on Dallas-Fort Worth, Charlotte, Miami, Phoenix, and other US gateways, plus international routes across the Atlantic, Latin America, and the Pacific. Its economics rest on three pillars: passenger ticket revenue, its high-margin AAdvantage loyalty and co-branded credit-card program (a major profit engine tied to its Citi and Barclays partnerships), and cargo. Like all legacy carriers, it carries heavy fixed costs for aircraft, fuel, and labor, which makes profitability sensitive to load factors, fares, and jet-fuel prices.
What does Delta Air Lines (DAL) do?
Delta Air Lines is a global network carrier headquartered in Atlanta, operating a hub-and-spoke system across domestic and international routes with major connecting points in Atlanta, Minneapolis, Detroit, Salt Lake City, and New York. Beyond passenger flying, Delta earns meaningful revenue from its co-branded credit card partnership with American Express, its SkyMiles loyalty program, cargo, and Delta TechOps, one of the largest aircraft maintenance, repair, and overhaul providers in the world. The company has leaned into premium seating (first class, Delta One, and Comfort+) as higher-income travelers have driven a larger share of demand.
AAL vs DAL: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- AAL drivers: Record revenue and premium mix; Loyalty and co-branded card economics.
- DAL drivers: Premium and loyalty revenue mix; High-income traveler demand.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: American carries one of the most leveraged balance sheets among US airlines, with an adjusted net-debt-to-capital ratio management has cited near 119%, well above peers like Delta and United. For DAL, airlines are deeply cyclical and sensitive to the broader economy, so a slowdown in consumer or corporate travel can quickly pressure fares and load factors.
AAL or DAL: which should you pick?
AAL vs DAL: the full fundamentals
AAL. American trades at a low market cap relative to its revenue, which is typical for airlines because heavy debt sits ahead of shareholders in the capital structure. The 2026 guidance range spanning a loss to a modest profit reflects how much depends on fuel prices and demand. The stock traded around $18 in early July 2026, off its 2026 highs, with analyst price targets clustered in a wide band.
DAL. Delta trades at a relatively low trailing earnings multiple, consistent with how the market typically values cyclical airlines. The March 2026 quarter showed record adjusted revenue of ~$14.2 billion even as total operating expense rose on higher fuel and refinery costs. Figures are approximate and drawn from company releases and market data as of mid-2026.
Headline figures (approximate, JULY 2026): AAL shows revenue (ttm) ~$55B, q1 2026 revenue ~$13.9B (record, +11% YoY), total debt ~$34.7B (below $35B, lowest since 2015), liquidity ~$10.8B; DAL shows revenue (fy2025) ~$63.4B, net income (fy2025) ~$3.8B, eps (fy2025) ~$5.82, market cap ~$61B.
The bottom line: AAL vs DAL
AAL and DAL are related but distinct: same themes, different businesses and risks.

FAQ
What is the difference between AAL and DAL?
+
American Airlines Group operates the world's largest airline by scheduled passengers and fleet size, flying a hub-and-spoke network centered on Dallas-Fort Worth, Charlotte, Miami, Phoenix, and other US gateways, plus international routes across the Atlantic, Latin America, and the Pacific. Delta Air Lines is a global network carrier headquartered in Atlanta, operating a hub-and-spoke system across domestic and international routes with major connecting points in Atlanta, Minneapolis, Detroit, Salt Lake City, and New York. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is AAL or DAL the better stock?
+
Neither is universally better; they suit different views and risk levels. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, AAL or DAL?
+
On forward P/E (as of August 2026), AAL trades at 6.08x and DAL at 9.87x, so AAL is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both AAL and DAL?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of AAL vs DAL?
+
AAL: American carries one of the most leveraged balance sheets among US airlines, with an adjusted net-debt-to-capital ratio management has cited near 119%, well above peers like Delta and United. Jet-fuel prices are the single biggest swing factor: a roughly $400 million adverse fuel impact hurt the first quarter alone, and full-year guidance was cut sharply from earlier in the year. Air travel is highly cyclical and exposed to recessions, weaker consumer or corporate demand, labor cost pressure, weather and operational disruptions, and industry price competition. The stock has been notably volatile, and a soft demand year combined with high fuel could push results back into losses. DAL: Airlines are deeply cyclical and sensitive to the broader economy, so a slowdown in consumer or corporate travel can quickly pressure fares and load factors. Jet-fuel prices are a large and volatile cost, and Delta's refinery segment adds its own commodity exposure (refinery expense rose sharply in the March 2026 quarter). Labor costs, capacity discipline across the industry, and heavy capital spending on new aircraft all affect margins. Non-operating items can also swing GAAP results, as seen when investment losses produced a reported net loss in the March 2026 quarter despite an operating profit. Geopolitical events, weather, and operational disruptions add further variability.
