Key Highlights
Omaha-based Berkshire Hathaway disclosed a new position in Delta Air Lines worth more than $2.6 billion in its latest quarterly filing, representing a significant reversal of the conglomerate’s previous stance on airline stocks. The stake makes Delta the 14th-largest holding in Berkshire’s equity portfolio as of March 31, 2026.
The investment comes after Berkshire famously sold its entire airline portfolio—including Delta, American Airlines, Southwest, and United—in April 2020, as the COVID-19 pandemic decimated air travel demand. At the time, Warren Buffett told shareholders that the airline industry had changed in ways that were “not good.”
The recent filing does not specify when during the first quarter the position was built, nor does it indicate whether Berkshire has added to other airline stocks. The investment in Delta alone suggests a reassessment of the sector’s long-term outlook. Delta’s stock has recovered significantly from its 2020 lows, benefiting from a sustained rebound in travel demand in recent years.
Berkshire’s return to airlines may also reflect evolving macroeconomic conditions, including easing fuel costs and a more stable operating environment for carriers. The filing offers no commentary from Buffett on the decision.

Expert Insights
Berkshire Hathaway’s re-entry into airline stocks after a years-long absence may signal a shift in the company’s assessment of the industry’s risk-reward profile. While the conglomerate had previously criticized airlines for their capital intensity and earnings volatility, recent improvements in cost control and pricing power could have made certain carriers more attractive.
The timing is notable given that airline stocks have generally performed well over the past several years, though the sector remains sensitive to fuel prices, labor costs, and macroeconomic conditions. The $2.6 billion stake represents a meaningful allocation but is modest relative to Berkshire’s total equity portfolio of roughly $300 billion.
Some market participants view the move as a potential value-seeking opportunity, as Delta has traded at a discount to historical valuation multiples relative to the broader market. However, the investment also carries the risk of renewed volatility from geopolitical events or a slowdown in travel demand.
Without direct commentary from Berkshire, the rationale remains speculative. The move could also reflect portfolio manager Todd Combs or Ted Weschler taking a more active role in sector allocation, as Buffett has increasingly delegated investment decisions in recent years. Investors will watch future filings for any evidence of additional airline positions.
