Warren Buffett Called Airlines the “Worst Sort of Business.” His Successor Just Built a $5.4 Billion Position Anyway.
Berkshire Hathaway's Greg Abel increased his stake in Delta Air Lines by 44% to 57 million shares, worth $5.4 billion, in Q2 2026. Delta's revenue now includes 61% from premium, loyalty, and Amex streams, differing from Warren Buffett's past critiques of the airline industry. Delta's stock has risen 44% over the past year, with a forward P/E of 13 and an analyst target of $105.31.

Why it matters

Market read
The filing provides fresh, material information on a major institutional allocation, offering a potential catalyst for Delta and insight into Berkshire’s sector tilt.
What to watch
Potential regulatory or macro‑economic headwinds (e.g., recession risk, travel demand slowdown) could offset premium revenue gains.
Background
Berkshire Hathaway, led by Greg Abel, added a substantial stake in Delta Air Lines after previously exiting other airline holdings, marking a strategic reversal of Warren Buffett’s historic view on the sector.
Ticker impact
Berkshire Hathaway increased its stake in Delta Air Lines to 57.3 million shares worth $5.4 billion, a fresh 13F disclosure.
Potential upside pressure as investors view the stake as a vote of confidence; short‑term rally possible.
The stake increase is sizable ($5.4 B) and represents the largest addition in the quarter, likely to influence market perception.
Berkshire Hathaway disclosed a $5.4 billion purchase of Delta shares in its August 14 2026 13F filing.
Minimal direct impact on BRK-B price; the news is more relevant for sector positioning.
While the purchase is large, Berkshire’s diversified portfolio dilutes any single‑stock effect on its own share price.
Market effects
Signals renewed investor confidence in airline premium revenue streams, potentially lifting other carriers.
U.S. airline sector may see increased buying pressure; broader market impact limited.
Highlights a shift in large‑cap fund allocations toward airline equities worldwide.
