Delta Air Lines (DAL) is back in focus after rising oil prices and fresh disruptions in the Middle East pressured the stock, as higher jet fuel costs and Tel Aviv flight suspensions weigh on investor sentiment.

The recent pullback, including a 2.2% 1 day share price decline and a 7% year to date share price return decline to US$64.25, contrasts with an 11.3% 1 year total shareholder return and a 72.2% 3 year total shareholder return. This suggests that longer term momentum has been stronger than the latest oil and geopolitical headlines imply.

With rising oil prices, Tel Aviv suspensions and a share price at US$64.25, some investors are wondering whether Delta’s recent weakness and its apparent discount signal an undervalued stock or whether the market is already pricing in future growth.

Most Popular Narrative: 1.6% Overvalued

According to a widely followed narrative from retail contributor PittTheYounger, Delta Air Lines' fair value sits at $63.21, slightly below the last close at $64.25, which frames the current pullback as less dramatic than recent headlines suggest.

Atlanta's flag carrier, so to speak, remains the lode star in the US network carrier heaven, with its profitability the current envy of the industry. Total revenue per available seat mile (TRASM) in Q4/25 stood at 21.94 cents, with total cost per available seat mile (CASM) at 19.93 cents. This yields a net profit of some 2 cents per available seat mile. This is simply outstanding, particularly for a legacy carrier. As such, Delta shares have kept climbing, possibly a bit too steeply even for results as strong as these.

The key point is that, as of now, the recovery from last year's "Liberation Day" shock is complete, with all the good news priced in. If recent signs of a deterioration of the underlying economic cycle in the US (that is, the economy apart from the warping effects of AI spending) were to solidify, conditions could become more challenging from here for transport stocks in general and airlines in particular.

Hence, I prefer to remain with both feet on the ground, raising my fair value per share to some 63 dollars, leaving no room for valuation to inflate even further. Far better, in my view, for Delta shares to lower their altitude a bit from here, allowing for a steeper climb later on. In financial parlance, that would mean realising some profits and keeping the rest of the position, with no additional buying for the time being.

If you want to see what sits behind that $63 range, the narrative walks through a tight mix of revenue growth, margin assumptions and a future profit multiple that might surprise you, especially for a legacy airline that still prices in a full earnings cycle.

Result: Fair Value of $63.21 (ABOUT RIGHT)

However, this story could change quickly if fuel costs rise further, or if weaker travel demand and a strained balance sheet start to bite harder than expected.

Another Angle: Market Pricing Looks Much Cheaper

That fair value of $63.21 suggests Delta is roughly in line with where it trades today, but the market is telling a different story when you look at earnings. The current P/E of 8.3x sits below both the global airlines average of 9.9x and a fair ratio of 17x that our model points to.

Put simply, the share price reflects a much lower earnings multiple than peers and where the fair ratio suggests it could settle over time. This may signal either caution about future profit trends or a possible gap if conditions hold up better than feared. Which side of that gap do you think the market is leaning toward?
