ALK vs UAL: Which Is the Better Buy in 2026?
Last updated August 2026
Short answer
UAL is the larger of the two ($39.38B market cap): the incumbent the market prices for continued execution (7.85x forward earnings, beta 1.26). ALK is the smaller challenger ($5.29B), priced similarly on forward earnings (7.93x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.
ALK vs UAL: 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 | ALK | UAL | What it tells you |
|---|---|---|---|
| Market cap | $5.29B | $39.38B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 7.93 | 7.85 | 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 | 1.28 | 1.26 | 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 | 44% of range | 68% 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. |
| Price / book | 1.44 | 2.36 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Before you buy: how ALK and UAL 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. ALK and UAL 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 ALK and UAL 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 Alaska Air Group (ALK) do?
Alaska Air Group operates Alaska Airlines, Hawaiian Airlines, and regional carrier Horizon Air, flying passengers primarily across the US West Coast, Hawaii, and expanding transpacific and long-haul routes. The company closed its roughly $1.9 billion acquisition of Hawaiian Airlines in September 2024 and reached a single operating certificate for the two carriers during 2025, and it runs a large loyalty and co-branded credit card franchise on top of the flying business.
What does United Airlines Holdings (UAL) do?
United Airlines Holdings is the parent of United Airlines, a full-service global network carrier that operates a hub-and-spoke model across major US gateways including Chicago, Denver, Houston, Newark, San Francisco, and Washington Dulles. It carries passengers and cargo worldwide, runs the MileagePlus loyalty program, and competes primarily against Delta and American among the large US network airlines. Trailing twelve-month revenue is roughly $60 billion, making it one of the largest airlines in the world by revenue.
ALK vs UAL: 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.
- ALK drivers: Hawaiian merger synergies; Loyalty and premium revenue.
- UAL drivers: Premium and cabin segmentation; MileagePlus loyalty economics.
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: Airlines are highly cyclical and capital intensive, so a slowdown in travel demand or a recession can quickly turn thin margins into losses. For UAL, airlines are deeply cyclical and capital intensive, so a weaker economy or softer travel demand can compress United's yields and load factors quickly.
ALK or UAL: which should you pick?
Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick ALK if you believe its drivers more; UAL if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the ALK and UAL guides.
ALK vs UAL: the full fundamentals
ALK. Revenue jumped in 2025 mainly because Hawaiian Airlines was consolidated for a full year, but profitability stayed thin and the first quarter of 2026 swung to a GAAP loss on higher fuel and one-time disruptions. Management suspended full-year 2026 guidance citing fuel price volatility. Investors are valuing the stock largely on expected merger synergies and a normalization of margins rather than on current trailing earnings.
UAL. United trades at a single-digit trailing earnings multiple, low relative to the broad market, which is typical for airlines given fuel volatility, capital intensity, and cyclical demand. Q1 2026 showed record quarterly revenue near $14.6 billion and net income around $699 million, and management guided full-year 2026 adjusted EPS to a wide $7 to $11 range that reflects genuine uncertainty about fuel and demand.
Headline figures (approximate, JULY 2026): ALK shows revenue (fy2025) ~$14.2B, revenue growth (2025 vs 2024) ~+21%, fy2025 gaap eps ~$0.18, fy2025 adjusted eps ~$0.43; UAL shows revenue (ttm) ~$60 billion, q1 2026 revenue ~$14.6 billion (up ~11% YoY), 2025 diluted eps ~$10.20, market cap ~$30 billion.
The bottom line: ALK vs UAL
ALK and UAL are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined ALK and UAL exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between ALK and UAL?
+
Alaska Air Group operates Alaska Airlines, Hawaiian Airlines, and regional carrier Horizon Air, flying passengers primarily across the US West Coast, Hawaii, and expanding transpacific and long-haul routes. United Airlines Holdings is the parent of United Airlines, a full-service global network carrier that operates a hub-and-spoke model across major US gateways including Chicago, Denver, Houston, Newark, San Francisco, and Washington Dulles. 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 ALK or UAL the better stock?
+
Neither is universally better. UAL is the larger incumbent; ALK is the smaller challenger and looks pricier on forward earnings. 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, ALK or UAL?
+
On forward P/E (as of August 2026), ALK trades at 7.93x and UAL at 7.85x, so UAL 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 ALK and UAL?
+
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 ALK vs UAL?
+
ALK: Airlines are highly cyclical and capital intensive, so a slowdown in travel demand or a recession can quickly turn thin margins into losses. Fuel price volatility is severe enough that Alaska suspended full-year 2026 guidance, and a spike directly compresses profitability. Merger integration carries execution risk, including labor harmonization, operational disruptions like those that hit Hawaii and Puerto Vallarta in early 2026, and the chance that synergy targets slip. The company also carries acquisition-related debt, and airlines broadly face labor cost inflation, weather and IT operational risk, and regulatory scrutiny. UAL: Airlines are deeply cyclical and capital intensive, so a weaker economy or softer travel demand can compress United's yields and load factors quickly. Jet fuel is a large and volatile cost that United cannot fully control, and spikes can erase margin gains. The company carries meaningful debt and faces unionized labor costs, aircraft delivery delays, and operational disruptions from weather or air-traffic constraints. Intense competition with Delta and American, plus low-cost carriers on domestic routes, limits pricing power, and the low earnings multiple reflects the market's skepticism that airline profitability stays elevated across a full cycle.
