Delta Air Lines (DAL) has drawn investor attention after announcing a multi year partnership with Amazon to equip 500 aircraft with Project Kuiper powered satellite Wi Fi, starting in 2028, to upgrade in flight connectivity.

After a sharp 5.21% 1 day share price return to US$66.48 on the Amazon Kuiper announcement, Delta’s momentum has cooled recently. However, its 1 year total shareholder return of 58.64% and 3 year total shareholder return of 102.00% still stand out.

With Delta delivering a 58.64% 1 year total return and trading at a reported 48.58% intrinsic discount, the key question is whether the Amazon Kuiper buzz leaves upside on the table or if the market is already baking in future growth?

Most Popular Narrative: 5.2% Overvalued

Delta closed at $66.48, while the most followed narrative on the stock pegs fair value around $63.21, giving a slight premium that still leaves room for debate.

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, thus yielding a net profit of some 2 cents per available seat mile. This is simply oustanding, particularly for a legacy carrier. As such, Delta shares have kept climbing, if a bit too steep even for results as stellar as these.

Want to see what keeps that fair value anchored near the current price? The narrative leans heavily on premium unit economics and a firm view on future profit multiples. Curious which revenue and margin assumptions quietly carry the weight here?

Result: Fair Value of $63.21 (OVERVALUED)

However, thinner margins, a strained balance sheet, and any shock to travel demand could quickly challenge assumptions about Delta’s current profit multiples.

Another View: DCF Sees Deep Value

While the popular narrative suggests Delta is about 5.2% overvalued around $66.48 versus a $63.21 fair value, our DCF model points in the opposite direction. On that framework, the shares trade at a 48.6% discount to an estimated $129.29 value. This raises a simple question: which story are you more comfortable underwriting?
