Warren Buffett has famously been one of the airline industry’s biggest critics. He has described aviation as a “bottomless pit” for investors, with an “insatiable” appetite for capital and once joked that an investor should have shot the first aircraft down had they foreseen the industry’s future losses.
Buffett’s argument hinged on airlines being treated as a commodity.
“In a business selling a commodity-type product,” he wrote at the time, “it’s impossible to be a lot smarter than your dumbest competitor.”
Which is why Berkshire Hathaway’s recent US$2.6 billion (AU $3.6 billion) investment in Delta Air Lines has raised eyebrows across both Wall Street and the aviation industry.
Notably, Buffett is no longer at the helm of Berkshire Hathaway, with the 95-year-old recently handing over the reins to Greg Abel. But the investment still marks a striking shift for a company that once exited airline stocks entirely during the COVID crisis.
Part of the appeal lies in Delta’s structural advantages. Unlike most airlines, Delta owns an oil refinery in Pennsylvania, giving it at least some protection against rising fuel costs.
The second is its increasing focus on premium travellers.
The carrier posted record revenue of US$14.2 billion (around AU$19.8 billion), up 9.4 per cent year on year. Earnings came in 40 per cent higher than the prior year, while free cash flow reached US$1.2 billion. Return on invested capital hit 12 per cent – a figure many airlines would struggle to achieve even in strong conditions.
Corporate bookings grew in double digits and reached a quarterly record. Premium cabin demand remained strong across both domestic and international routes.
Revenue from Delta’s co-branded American Express partnership – perhaps the clearest sign of how deeply the airline has embedded itself into the spending habits of higher-income travellers – rose 10 per cent to US$2 billion for the quarter, driven by 12 per cent growth in card spend.
Nearly half the seats on Delta’s newest aircraft are now configured as premium. On the planes being retired, that figure sat closer to 30 per cent. The fleet itself is being reshaped around a simple bet: the traveller willing to pay more is the traveller worth chasing.
“Our consumers are continuing to prioritise experiences, with travel among the top spending categories,” Delta CEO Ed Bastian told analysts on the earnings call.
What Delta appears to be betting on is that premium travel demand is no longer cyclical, but structural.
There is now a sizeable cohort of travellers for whom flying business class – or at minimum paying for extra legroom, lounge access and reliability – is no longer viewed as an occasional luxury, but an expected standard of travel.
That cohort extends beyond the ultra-wealthy. It includes corporate travellers, loyalty-point maximisers and aspirational middle-class consumers increasingly willing to spend more on comfort and experience.
For decades, airlines competed largely on price. Delta is betting the future of aviation profitability may instead lie in convincing passengers not to trade down.
