Key Highlights
Warren Buffett’s Berkshire Hathaway has quietly returned to the airline industry, with a newly disclosed $2.6 billion stake in Delta Air Lines. According to a recent regulatory filing, the Omaha-based conglomerate built the position during the first quarter of 2026, making Delta its 14th-largest holding as of March 31.
The move represents a striking reversal for Buffett, who famously sold all of Berkshire’s airline holdings in 2020 during the height of the COVID-19 pandemic, saying the industry’s future had become too uncertain. At the time, Berkshire owned stakes in Delta, United Airlines, American Airlines, and Southwest Airlines.
The $2.6 billion investment in Delta comes as the airline sector has rebounded strongly in the post-pandemic era, with travel demand surging and carriers reporting improved profitability. Berkshire’s latest filing did not specify the exact number of shares purchased, but the size of the stake suggests a substantial bet on Delta’s recovery and long-term prospects.
Delta Air Lines shares have rallied in recent weeks, partly driven by robust earnings and optimism around summer travel. The airline reported a solid first quarter earlier this year, with revenue exceeding analyst expectations. Berkshire’s entry could further boost investor sentiment toward the sector.
The purchase is part of a broader trend of Berkshire rotating into more cyclical businesses in 2026, as the conglomerate has also added positions in energy and consumer goods. The filing also showed that Berkshire trimmed some of its larger stakes, including Apple and Bank of America, to fund the Delta purchase.

Expert Insights
Berkshire Hathaway’s renewed exposure to airlines suggests that Warren Buffett and his investment team see value in the sector after a period of turbulence. The $2.6 billion Delta stake is sizable but remains a small fraction of Berkshire’s total equity portfolio, which exceeds $300 billion.
The airline industry has shown strong earnings recovery in 2025 and early 2026, driven by booming leisure and business travel. Delta, in particular, has been praised for its operational discipline, strong balance sheet, and premium customer focus. However, the sector remains sensitive to fuel costs, labor disputes, and macroeconomic shifts.
Given Buffett’s long-term horizon, the investment may indicate that Berkshire believes Delta’s competitive advantages could generate sustainable returns over the next decade. Still, investors should note that airlines have historically been volatile and capital-intensive, and Berkshire’s previous exit in 2020 shows the risks are real.
The lack of specific price data in the filing means the exact entry point is unknown, but the stake was likely built gradually through market purchases. Analysts suggest that Berkshire may have taken advantage of weakness in airline shares earlier in the year. The move could also be a hedge against inflation, as airlines tend to benefit from rising fares in a strong economy.
As always, Berkshire’s moves are closely watched by the market, and this latest filing adds a new dimension to the conglomerate’s evolving investment strategy.
