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

A Discounted Cash Flow, or DCF, model estimates what Delta Air Lines stock could be worth by projecting the company’s future cash flows and then discounting them back to today’s value. The focus is on the cash that could be available to shareholders over time, expressed here in $.

Delta Air Lines most recent last twelve months free cash flow is about $3.09b. Analysts have provided forecasts for the next few years, and Simply Wall St extends those into longer term projections using a 2 Stage Free Cash Flow to Equity model. By 2029, projected free cash flow is $4.60b, with intermediate years such as 2026 and 2027 projected at $2.36b and $3.83b respectively, before further extrapolated figures out to 2035.

When all these future cash flows are discounted back and added together, the model arrives at an estimated intrinsic value of $105.24 per share. Compared with the recent share price of $84.07, the DCF output suggests Delta Air Lines is trading at about a 20.1% discount, which points to the stock being undervalued on this measure.

Approach 2: Delta Air Lines Price vs Earnings

For profitable companies like Delta Air Lines, the P/E ratio is a commonly used way to compare what you pay for each dollar of earnings with other stocks. Investors typically look for a higher P/E when they expect stronger growth or see lower risk, and a lower P/E when they expect slower growth or higher risk. So what counts as a “normal” P/E depends on a mix of growth expectations and perceived stability.

Delta Air Lines currently trades on a P/E of 12.27x. This sits above the Airlines industry average of 9.41x, but well below the broader peer average of 24.29x. Simply Wall St also calculates a “Fair Ratio” of 19.10x for the stock, which is the P/E level that would be expected given factors such as Delta’s earnings growth profile, industry, profit margins, market cap and key risks.

This Fair Ratio is more tailored than a basic comparison with peers or the industry because it attempts to account for what Delta Air Lines specifically offers and the risks it carries. Comparing the Fair Ratio of 19.10x with the current P/E of 12.27x suggests the stock is trading below that Fair Ratio benchmark.

Result: UNDERVALUED
