Elon Musk and Ryanair CEO throw jabs over Starlink integration

SpaceX Founder and CEO Elon Musk and Ryanair CEO Michael O Leary has fired new shots in the latest round of heated engagement.

The dispute between Ryanair CEO Michael O’Leary and Elon Musk, along with the Starlink team, centers on whether Ryanair should install Starlink satellite internet on its fleet of Boeing 737 aircraft.

The exchange unfolded publicly on X in mid-January 2026, with different views on technical feasibility, costs, and passenger demand for in-flight connectivity.

It began when reports surfaced that Ryanair had ruled out equipping its planes with Starlink. O’Leary cited the added weight and aerodynamic drag from the antenna, estimating a 2% increase in fuel consumption.

He argued this would impose high extra costs—potentially hundreds of millions annually—on the airline’s short-haul flights, which average about one hour. He also stated that passengers on these brief routes would be unwilling to pay for Wi-Fi, making the investment unviable for a low-cost carrier focused on keeping fares minimal.

Elon Musk responded via his social media platform X, describing O’Leary as “misinformed.” Musk pointed out that the fuel impact would be negligible and difficult to measure accurately on short flights, particularly during climb phases where the aircraft’s high angle of attack reduces effective drag. He added that Starlink’s design offers efficiency advantages over older connectivity systems.

Starlink’s VP of Engineering, Michael Nicolls, provided more detail in a post, explaining that a 2% fuel penalty might apply to bulkier legacy satellite terminals, but Starlink’s low-profile, thinner antenna results in only about 0.3% increased fuel use on a Boeing 737-800 (which burns roughly 800 gallons per hour). Nicolls also challenged the notion that passengers do not want reliable in-flight Wi-Fi.

Musk escalated the rhetoric in follow-up posts, calling O’Leary an “utter idiot” and urging Ryanair to “fire him.” In a subsequent reply, Musk stated that O’Leary’s fuel impact calculation was wrong by a factor of 10 and that he refused to consider physics-based estimates or real-world measured data from 737s already equipped with Starlink. Musk reiterated his call to dismiss the CEO, labeling him an “imbecile.”

The back-and-forth drew widespread attention on X, with users sharing clips of O’Leary’s earlier interview comments, which dismissed Musk’s knowledge of aviation dynamics and drag. At the same time, Musk’s supporters highlighted Starlink’s adoption by other airlines.

The core disagreement remains technical—drag and fuel effects—combined with business strategy: Ryanair prioritizes cost control on short routes, while Musk and Starlink emphasize minimal impact and growing passenger expectations for connectivity.
