Ed Bastian, chief executive of Delta Air Lines, denied reports of a public feud with Tesla CEO Elon Musk.

Business Insider reported on Oct. 9 that Bastian, in an interview with CNBC, drew a line under recent criticism of Delta by Musk on X, formerly Twitter, saying there was no personal conflict.

“At least from my side, there’s no back-and-forth fight,” Bastian said. “I’m a big fan of Starlink, and I like what Elon is doing. I drive a Tesla too.” He added, “Talk that this is some kind of personal issue is completely untrue.”

The sparring appears to have started with Delta’s decision on inflight internet suppliers. Delta in March chose Amazon’s LEO as its next-generation satellite internet provider instead of SpaceX’s Starlink. Musk at the time posted to the effect that Delta “does not realise how much this will affect them.”

Over the past 2 weeks, Musk’s criticism has continued more bluntly. That came after an X account focused on the airline industry, JonNYC, posted unverified quotes and attributed them to Bastian. The post included the sentence, “We don’t want to be with Elon Musk. Trust me,” and Musk reposted an article containing it, writing that “Bastian will be fired over this.”

Musk then posted several more times mocking Delta’s choice for internet service. In late September, he wrote, “The best way to lock AI in a sandbox is to put it on a Delta flight,” deriding the quality of Delta’s inflight internet. The outlet said the remarks attributed to Bastian by JonNYC were unverified.

Bastian chose not to respond head-on. Asked about it in the CNBC interview, he said, “I don’t care at all. Everyone has the right to their opinion.” Delta did not immediately respond to a request for comment.

This is not the first time Musk has engaged in a public war of words with airline executives. In January, he sparred on X with Michael O’Leary, chief executive of European low-cost carrier Ryanair, over adopting Starlink. Ryanair did not install Starlink on its aircraft due to cost issues, and Musk even posted a poll asking X users whether he should buy Ryanair. O’Leary responded by offering discounted seat sales for “great idiots.”

The episode shows that an airline’s choice of inflight connectivity services can go beyond a simple technology adoption and turn into an open dispute between platform operators and airlines. Delta became a target of Musk’s criticism after choosing Amazon LEO instead of Starlink, but the company’s chief executive appears to be keeping his distance from framing it as a personal confrontation.
