Greg Abel, who assumed Berkshire Hathaway’s chief executive role in January, has steered the conglomerate back into airline equities with a fresh $2.6 billion purchase of Delta Air Lines stock in the first quarter. The move revives a pattern of periodic airline bets that date back to Warren Buffett’s own, often‑oscillating, forays into the sector. Analysts say the purchase could add modest pressure on Delta’s share price amid tight industry valuations.

Buffett told the Wall Street Journal he played no part in the Delta transaction, but confirmed he had offered Abel broader investment ideas earlier this year. Those suggestions likely shaped the portfolio tilt toward carriers, a segment Buffett once dismissed as a “boom‑and‑bust” arena yet revisited as travel demand rebounds post‑pandemic. The airline’s recent earnings beat also sweetened the appeal for value‑focused investors.

The fresh stake lifts Berkshire’s airline exposure to roughly 1% of Delta’s market cap, nudging the conglomerate’s overall equity mix toward the travel sector. Investors will watch whether Abel’s confidence translates into higher returns, especially as airlines grapple with rising fuel costs and capacity constraints. Berkshire’s renewed bet underscores a willingness to re‑engage with a historically fickle industry, and with Berkshire’s capital behind it, Delta may find leverage for future network expansion.
