Approach 1: Delta Air Lines Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what a stock could be worth by projecting future cash flows and discounting them back to today using a required return. It is essentially asking what those future dollars are worth in today’s terms.

For Delta Air Lines, the model used is a 2 Stage Free Cash Flow to Equity approach. The latest twelve month Free Cash Flow is about $3.1b. Analyst and extrapolated projections, expressed in today’s dollars, range from about $2.2b in 2026, and from $2.1b to $3.3b across 2027 to 2035, with Simply Wall St extending the forecasts beyond the analyst horizon.

When all those discounted cash flows are summed, the DCF model points to an estimated intrinsic value of about $106.46 per share. Compared with the recent share price of around $76.14, this implies the stock trades at roughly a 28.5% discount, which suggests Delta Air Lines is undervalued on this model.

Approach 2: Delta Air Lines Price vs Earnings

For profitable companies, the P/E ratio is a useful yardstick because it links what you pay directly to the earnings the business is already generating. It helps you see how much the market is currently willing to pay for each dollar of profit.

What counts as a "normal" or "fair" P/E usually reflects how the market views a company’s growth outlook and risk profile. Higher expected growth or lower perceived risk can justify a higher P/E, while slower growth or higher risk often goes with a lower P/E.

Delta Air Lines currently trades on a P/E of 11.12x, compared with an Airlines industry average of about 8.91x and a broader peer average of 21.64x. Simply Wall St’s Fair Ratio for Delta is 18.10x. This Fair Ratio is a proprietary estimate of what the P/E might be given factors such as earnings growth, industry, profit margin, market cap and risk, rather than just a simple comparison with peers.

Because the Fair Ratio of 18.10x is higher than the current P/E of 11.12x, the stock screens as undervalued on this metric.

Result: UNDERVALUED

Upgrade Your Decision Making: Choose your Delta Air Lines Narrative

Earlier it was mentioned that there is an even better way to understand valuation, so this is where Narratives come in as a simple way for you to connect your view of Delta Air Lines with the numbers behind it.

A Narrative is your story about a company, translated into concrete assumptions like fair value, future revenue, earnings and margin estimates, instead of just relying on a single price target or ratio in isolation.

On Simply Wall St’s Community page, Narratives help you link Delta’s business story to a forecast and then to an estimated fair value. This allows you to compare that fair value with the current share price and decide whether you see the stock as fully priced, expensive or cheap for your own portfolio rules.

Because Narratives on the platform update when fresh information comes in, such as earnings or sector news, they can keep your Delta view current without you rebuilding a model every time conditions change.

For example, one Delta Narrative on Simply Wall St assumes a fair value of about US$49 per share with lower revenue growth and a future P/E of 11. A more optimistic Narrative assumes fair value of about US$95 with revenue growing closer to 8% and a future P/E of about 13.6. Seeing those side by side shows you how different assumptions can lead to very different conclusions about the same stock.
