American Airlines (AAL) Valuation in Focus Following STARLUX Partnership and Pacific Expansion

Simply Wall St

American Airlines Group (AAL) just landed a major deal that could catch the eye of any investor thinking about the airline’s future. The carrier has teamed up with STARLUX Airlines in a partnership that unlocks single-ticket bookings and easier connections between North America and Taipei, just as STARLUX launches its new Taipei-Phoenix route. For travelers, this means an easier way to fly across the Pacific. For American Airlines, it marks a strategic expansion of their international playbook, leveraging Phoenix as a powerful new gateway to Asia.

This news comes as American Airlines’ stock has shown some real momentum. The past three months saw shares rise more than 21%, a sharp rebound compared to its year-to-date decline. Over the last year, the stock has returned 30%, though its longer-term results remain mixed. Recent announcements, including service expansions in Quebec City and new international partnerships, suggest a company slowly but surely strengthening its network reach and competitive positioning in important markets.

With American making a significant international move and the stock rallying, investors may be considering whether this signals the start of a market reappraisal, or if the potential is already priced in. Here’s a closer look at what the valuation reveals.

Most Popular Narrative: 87% Overvalued

The dominant narrative, according to PittTheYounger, challenges the bull case for American Airlines with a strong statement that the stock is meaningfully overvalued in comparison to its fair value estimate.

There is a single reason why American is the least attractive of US legacy carriers, at least from an investment standpoint: its balance sheet. While most airlines, particularly in the US, carry significant debt, American has gone further and now reports negative equity. Any startup with a balance sheet like this would not survive.

Is American ready to soar? The main assumptions behind this perspective center on the company’s financial structure and the impact of a potential downturn in demand. What underlying numbers support the claim of significant overvaluation? PittTheYounger’s analysis explores the interaction between balance sheet concerns and profit margin forecasts. To understand why the fair value estimate is so much lower, the full story is recommended reading.

Result: Fair Value of $7.23 (OVERVALUED)

However, unexpected travel demand or stronger cost controls could challenge the overvaluation thesis. This may trigger a reexamination of American’s true potential.
