Berkshire Hathaway has built a new position in Delta Air Lines worth more than $2.6 billion, marking the conglomerate’s return to airline investing after exiting the sector during the pandemic. The stake makes Delta Berkshire’s 14th-largest holding as of the end of the first quarter, according to a recent filing.
Live News
Warren Buffett’s Berkshire Hathaway has quietly re-entered the airline industry, taking a substantial stake in Delta Air Lines valued at over $2.6 billion. The position, disclosed in a regulatory filing, was built during the first quarter of 2026, making Delta the 14th-largest equity holding in Berkshire’s portfolio.
The move signals a notable reversal for the Omaha-based conglomerate, which famously sold off its entire airline portfolio in early 2020 during the COVID-19 pandemic. At that time, Buffett cited “the wrong bet” on an industry facing unprecedented disruption. Since then, U.S. airlines have steadily recovered as travel demand rebounded, though challenges such as fuel costs and operational volatility remain.
Berkshire’s new Delta stake comes as the airline has been focusing on debt reduction, fleet modernization, and strengthening its premium offerings. The exact number of shares purchased has not been disclosed, but the $2.6 billion valuation suggests a significant bet on Delta’s long-term trajectory. Berkshire has not publicly commented on the rationale for the investment.
The filing covers positions held as of March 31, 2026. Delta Air Lines shares have been trading with increased volume in recent sessions following the news, though Berkshire has not indicated any intention to increase or reduce the stake further.

Expert Insights
The re-entry into airlines suggests that Berkshire Hathaway sees long-term value in Delta Air Lines despite the sector’s historical volatility. While Berkshire has traditionally favored businesses with durable competitive advantages, airlines have often been viewed as capital-intensive and cyclical. However, Delta’s post-pandemic recovery—including reduced debt, a younger fleet, and strong hub network—may align with Berkshire’s preference for companies that generate consistent cash flows.
Investors should note that Berkshire’s filing reflects positions as of late March, and there is no guarantee the stake has been maintained or adjusted since then. The lack of any public commentary from Berkshire means the investment rationale remains open to interpretation. Some analysts speculate the move could be related to Delta’s growing premium-segment revenue and international route expansion.
From a portfolio perspective, the Delta position adds a cyclical component to Berkshire’s holdings, which are heavily weighted toward Apple, Bank of America, and other large-cap stocks. This diversification may help balance Berkshire’s exposure, but it also introduces more economic sensitivity. The long-term performance of the stake will likely depend on Delta’s ability to manage fuel costs, maintain pricing power, and navigate any future disruptions.
As always, investors should consider such news as one data point and avoid making hasty portfolio changes. Berkshire’s moves often reflect a multiyear horizon, and this investment may take time to prove its merit.
