Berkshire Hathaway increased its stake in Delta Air Lines by 44% in the second quarter, ending June with 57.3 million shares valued at about $5.37 billion. The move came as Greg Abel continued to deploy Berkshire’s cash pile and extended a renewed bet on airlines, a sector Warren Buffett had largely avoided after the pandemic sell-off.
Berkshire added 17.5 million Delta shares during the quarter, according to its latest portfolio filing. The position was first rebuilt earlier in 2026 and then expanded again between April and June, making the latest increase a continuation of Berkshire’s return to the carrier rather than a fresh entry.
The Delta holding was one of several changes in a quarter of active portfolio reshuffling. Berkshire also increased its Alphabet stake sharply, while trimming or exiting other positions, highlighting a broader redeployment of capital from its U.S. equity portfolio.
