Buffett’s back on Delta, and airlines are buzzing

Buffett’s airline U-turn

Warren Buffett once treated airlines like the expensive baggage fee of investing — tolerated, then quickly regretted. So Berkshire Hathaway popping up with a brand-new 39.8 million-share Delta Air Lines stake is the kind of move that makes the whole market do a double take.

What changed?

The new position, disclosed in Berkshire’s latest 13F filing, was valued at roughly $2.65 billion. That’s not a casual nibble; that’s a full-on entrée. And when Buffett-sized money walks back into a sector it previously fled, people start wondering whether the worst is over or if the buffet line is just getting started.

For Delta, the signal matters because airline stocks still tend to trade like a roller coaster with turbulence:

• fuel costs can whipsaw margins
• demand can cool fast if the economy stumbles
• and pricing power is only as good as travelers’ willingness to keep swiping their cards for a window seat

Why investors care

A Berkshire stake doesn’t magically fix the airline business, but it can change the vibe around a stock. Delta now gets a credibility boost, and that can matter when the market is trying to decide whether carriers are durable cash machines or just one bad quarter away from seatback panic.

The bigger question: is Buffett betting on Delta specifically, or just on a travel rebound with a cleaner balance sheet than the average carrier? Either way, the message is clear — one of the market’s most famous skeptics just bought a ticket back onto the plane.

Big picture: when Berkshire changes its mind, Wall Street usually listens. And this time, Delta is the one in the cockpit.
