Key Highlights
Berkshire Hathaway has re-entered the airline sector with a substantial stake in Delta Air Lines, according to a recent regulatory filing. The Omaha-based company accumulated a position worth more than $2.6 billion by the end of March, positioning Delta as Berkshire’s 14th-largest equity holding.
The investment represents a sharp pivot from 2020, when Berkshire sold its entire holdings in major U.S. carriers—including Delta, American Airlines, Southwest, and United—after the pandemic decimated air travel. At the time, Buffett cited industry uncertainty and described the decision as a "mistake" for holding airlines.
This latest filing, which covers Berkshire’s U.S.-listed equity portfolio as of March 31, does not disclose the exact number of shares purchased or the average price paid. Delta Air Lines has not commented on the stake. Berkshire also increased its position in other sectors during the quarter, including energy and consumer goods.

Expert Insights
Berkshire Hathaway’s re-entry into airlines suggests a shift in Warren Buffett’s assessment of the sector’s risk profile, according to financial observers. The decision may reflect improved airline balance sheets, greater pricing discipline, and a more consolidated industry structure compared to the pre-pandemic era.
Delta, in particular, has shown resilience in recent quarters, benefiting from strong premium travel demand and cost-control measures. However, the airline remains exposed to fuel price volatility, labor costs, and potential economic slowdowns.
Analysts caution that Berkshire’s investment does not necessarily signal a full-scale return to airline investing—it could be a focused bet on Delta’s competitive advantages. The lack of disclosure on purchase timing means the average entry price is unknown, making it difficult to assess the current gain or loss on the position.
Investors may watch for any subsequent filings showing further additions or reductions. For now, the $2.6 billion stake underscores Berkshire’s willingness to revisit industries it once shunned, while reminding markets that large, patient capital can surprise the consensus.
