This Underrated Stock Is Up More Than 75% Over the Last 12 Months -- and It Could Keep Rising

Delta reported record Q1 2026 operating revenue of $14.2 billion, up nearly 10% year over year, with adjusted EPS of $0.64, up 44%. High-margin premium and loyalty revenue accounted for 62% of sales, free cash flow reached $1.2 billion, and management paid down $1.6 billion of debt, cutting adjusted net debt to $13.5 billion. The company expects to generate $1 billion in profit in the June quarter, while the stock trades at about 10.5x earnings, supporting a constructive valuation case.

Analysis

The market is likely underappreciating that DAL’s mix shift is not just a margin story but a duration story: more earnings are now tied to premium leisure, business travel, and payment economics than to the weakest part of the fare curve. That reduces cyclicality at the point where airline equities usually deserve the lowest multiples, which explains why the stock can keep rerating even after a large move. The second-order implication is that competitors with less premium cabin density and weaker loyalty monetization will have to lean harder on price to defend share, which should compress industry yields before it shows up in headline traffic data.

The real catalyst path is not a one-quarter beat; it is a multi-quarter compounding of fee-like cash flows and balance-sheet repair. If management keeps converting operating cash into debt reduction at the current pace, equity value becomes more levered to modest multiple expansion than to heroic earnings growth. That matters because a stock at ~10x earnings does not need an airline supercycle to work — it only needs the market to stop assigning a recessionary discount to a business that is behaving increasingly like a consumer payments-plus-travel platform.

The main risk is that the consensus extrapolates premium demand too cleanly into the back half of the year. Premium seats and loyalty spend can soften quickly if corporate travel budgets roll over or if consumers trade down after a travel-heavy season, and airlines are still exposed to fuel and disruption shocks that can hit margins faster than revenue can reprice. The overlooked bearish scenario is not a collapse in demand, but a normalization of the current mix premium, which would expose how much of the multiple expansion is already predicated on persistence.

Key Decisions for Investors

• Maintain a tactical long DAL position into the next 1-2 earnings prints; upside remains driven by continued mix improvement and debt paydown, with limited valuation support downside below the low-teens multiple only if premium demand cracks.
• Pair trade: long DAL / short a lower-quality legacy carrier basket over 3-6 months to express the view that premium and loyalty monetization will widen the operating margin gap across the industry.
• For event-driven accounts, buy DAL call spreads 3-6 months out rather than outright calls; the risk/reward is best if the market keeps rerating the stock on cash flow durability rather than a straight-line earnings surprise.
• Use any post-earnings pullback tied to fuel or macro chatter as an entry opportunity, but size modestly: the setup is attractive, yet airline beta remains high and a 1-quarter demand miss can unwind 2-3 quarters of multiple expansion.
