Southwest Airlines (LUV) Stock May Still Be A Bargain As Profit Outlook Falls

Southwest Airlines has seen its stock climb sharply in recent years, and the latest profit reset alongside higher fuel costs puts a fresh spotlight on whether that share price still lines up with what the airline actually earns. With investors weighing record revenue against rising expenses, the question now is how well the current valuation reflects the company’s earnings power.

• Over the past 3 years the stock has returned 96.6%, which puts real weight on whether the current valuation is being driven by earnings strength or by optimism that may not be fully tied to profits.
• The cut to the 2026 profit outlook in response to higher jet fuel prices suggests that future margins and cash generation may be more sensitive to cost swings than the recent run in the share price might imply.

Is Southwest Airlines Still Cheap on Earnings?

The P/E ratio works well for Southwest Airlines because management still guides investors using earnings per share targets. On this lens, the stock trades on roughly 20.2x earnings, which is above the airlines sector average of about 12.1x and also higher than the peer group on roughly 10.6x.

Because the Fair Ratio framework adjusts for Southwest Airlines' own growth profile, profitability and risk, it points to a higher P/E than the market currently assigns, so the shares screen as undervalued on this model. Despite the cut to the 2026 profit outlook in response to rising jet fuel costs, the current multiple still sits below what that tailored benchmark suggests might be justified by the business economics.
