Using an unlevered Free Cash Flow to Firm (FCFF) model, we project Southwest Airlines Co.'s cash flows over 5 years with line-by-line expense modeling. Revenue is projected revenue growing from 15.6% to 10.4% annually, with expenses (COGS, SG&A, R&D) held at historical ratios. Depreciation is computed from a vintage matrix based on a 5-year useful life. Working capital is modeled using historical turnover days (DSO 19, DPO 5, DIO 14). At a 7.4% WACC with mid-year discounting, the terminal value (80% of enterprise value) is derived from the Gordon Growth Model on Year 6 FCFF at a 2.5% perpetual rate. After subtracting net debt, the equity value implies a fair price of $116.13 per share, suggesting LUV is undervalued by 194.7% at the current price of $39.41.

Using the PEG framework with analyst consensus forward EPS growth of 25.0% plus 2.1% dividend yield, the company has a fair value of $67.47 based on NTM EPS (FY2026) of $2.70. The current PEG ratio is 0.25.
PEG < 1 = bargain, 1–1.5 = fair, > 2 = expensive.
Growth above 25% is capped — hypergrowth may not be sustainable long-term.
