Investing in airlines has never made sense. As Warren Buffet once said “if a far-sighted capitalist had been present at Kitty Hawk, he would have done his successors a huge favor by shooting Orville down.” Buffet never liked airline stocks, but did see a possible entry point after years of consolidation to make an investment in Delta which he followed through on. That’s now a distant memory as Berkshire recently cashed out their holding following the pandemic. It’s for this reason that you haven’t, and won’t, see startups getting into the airline business; it’s too competitive and capital intensive with meager margins to make the business attractive to growth stage investors. But you are seeing aviation tech on the fringes of the industry attract VC money. Jetblue Technology Ventures, for example, has made numerous investments in the travel sector.
