Berkshire Hathaway, under the leadership of CEO Greg Abel, has reportedly built a new investment position in Delta Air Lines during Abel’s initial quarter as chief executive. The move signals a potential shift in the conglomerate’s airline strategy after exiting major carriers during the pandemic. No financial details or share counts have been disclosed.
Live News
Berkshire Hathaway has made a fresh investment in Delta Air Lines, marking the first major portfolio move under new CEO Greg Abel, according to a report from The Wall Street Journal. This investment comes during what would be Abel’s first quarter officially leading the conglomerate.
The decision to invest in Delta represents a notable reversal for Berkshire, which sold off its holdings in major U.S. airlines — including Delta — in 2020 amid the Covid-19 pandemic. At the time, Chairman Warren Buffett expressed regret over the investment and said Berkshire would not buy airline stocks again.
However, the investment under Abel suggests a possible reassessment of the airline sector. The exact size, price, and timing of the purchase have not been disclosed. The report did not specify whether the investment was made by Buffett, Abel, or Berkshire’s investment managers Todd Combs and Ted Weschler.
Berkshire Hathaway’s next detailed 13F filing, which will reveal equity holdings, is expected in the coming weeks. The filing should provide clarity on the Delta stake and any other portfolio changes made during the quarter.
Neither Berkshire nor Delta has commented publicly on the transaction.

Key Highlights
- Leadership transition context: Greg Abel assumed the CEO role earlier this year, succeeding Warren Buffett as part of a long-planned succession. This Delta investment is one of the first portfolio actions associated with Abel’s tenure.
- Airline sector pivot: Berkshire previously liquidated its airline positions in 2020, calling the businesses unattractive during a pandemic. The new Delta stake suggests a re-evaluation of the airline’s recovery prospects and valuation.
- Investment rationale: While no specific data is available, the move could reflect a view that Delta has strengthened its balance sheet, improved operational efficiency, or that airline valuations have become more compelling.
- Market implications: The news has fueled speculation about broader Berkshire portfolio shifts and whether other previously divested sectors could return to favor. The 13F filing will be closely watched by analysts.
- Delta’s recent performance: In its latest available earnings release (first quarter 2026), Delta Air Lines reported results that met or exceeded Wall Street expectations, though no specific figures are cited here. The company continues to benefit from strong travel demand.

Expert Insights
The reported investment in Delta by Berkshire Hathaway under Greg Abel’s leadership may signal a pragmatic, rather than dogmatic, approach to capital allocation. While Buffett famously soured on airlines, Abel may be open to opportunistically re-entering the sector if valuations and fundamentals align.
Analysts suggest that Delta’s current market position — with a strong network, cost discipline, and improving free cash flow — could appeal to value-oriented investors. However, without knowing the size of the stake, it is difficult to gauge Berkshire’s conviction level.
Some market observers caution that this could be a small, exploratory position rather than a major bet. Berkshire’s 13F filing will provide critical context, including whether the position was built alongside other airline holdings.
Investors should note that Berkshire’s portfolio moves are not always predictive of broader market trends. The conglomerate often invests with a multi-year horizon, and the Delta stake may take years to fully play out.
As with any investment, past decisions do not guarantee future outcomes. The airline industry remains subject to fuel price volatility, labor costs, and macroeconomic cycles. The move should be viewed as part of Berkshire’s evolving strategy under new leadership.
