Put WiFi airplanes consume a lot of fuel? The trolling between Elon Musk and Ryanair which ended in Elon's interest in purchasing the airline.
In the world of aviation, Every gram of weight and every millimeter of aerodynamic drag translates into dollars. for years, Michael O’Leary, the controversial CEO of Ryanair, has refused to install WiFi in its fleet under a simple argument: satellite dishes are heavy, bulky and increase fuel consumption by up to 2%.
"It includes a penalty of 2 % in fuel consumption due to weight and resistance. "We don't think our passengers are willing to pay for Wi-Fi for an average one-hour flight."
Nevertheless, a recent interaction in X (before Twitter) suggests the future of air connectivity could be about to change thanks to Starlink engineering.
The debate: A luxury too expensive?
It all started when the efficiency of traditional antennas compared to the new generation of terminals was discussed. Starlink. Sawyer Merritt highlighted that Starlink aviation antennas are drastically thinner, which reduces wind resistance.
That's when Michael Nicolls, Starlink VP of Engineering, intervened to disprove the old myth of 2% fuel penalty:
«An impact of 2% in fuel may be true for older terminals, but the Starlink terminal has a much lower profile and is more efficient. Our analysis shows that the increase in fuel for a Boeing 737-800 (that consumes 800 gallons per hour) with our current design it is approximately 0.3%.
Pair Elon Musk, a 0.3% there is still room for improvement. In the same conversation, Musk made his technical ambition clear by responding with a specific goal for his engineering team.:
«Hmm, "There must be a way to lower that below 0.1%.".
This difference is crucial. While traditional airlines can absorb a small increase in costs in exchange for improving the passenger experience, for an ultra-low-cost airline like Ryanair, reduce the impact of 0.3% al 0.1% could be the decisive factor to finally make the leap to full connectivity.
«I will buy Ryanair»
The interaction did not stop only in technical numbers. Faithful to his disruptive style, after the exchange of opinions on the efficiency, costs, fall of X and the resistance of low-cost airlines to adopt new technologies, Elon Musk closed the conversation with a statement that lit up the networks.
Given the friction between Starlink's technological vision and the Irish airline's extreme savings mentality, Musk even said that he was interested in buying Ryanair.
Although this is probably one of his characteristic jokes, the underlying message is serious: Starlink is not just building satellites, is redesigning the aerodynamics of commercial aviation so that WiFi stops being a fuel “ballast” and becomes an invisible standard.
But the drama did not stop there and even Ryanair with its CEO offered a press conference to talk about the situation and of course, make fun of Elon…
WiFi costs
To understand why Elon Musk wants to lower the carbon footprint of the 0.3% al 0.1%, you have to look at the mathematics behind a commercial fleet.
Taking as a basis a Boeing 737-800 (Ryanair's workhorse) and fuel prices projected for the beginning of 2026 (ca.. $2.15 USD per gallon in wholesale markets), the calculation for an average flight of 3 hours would be the following:
| Antenna Technology | Impact on Consumption | Extra Gallons | Additional Cost (USD) |
| Legacy (old antennas) | 2.0% | 48 gal | $103.20 |
| Starlink (Current design) | 0.3% | 7.2 gal | $15.48 |
| Meta de Musk (<0.1%) | 0.1% | 2.4 gal | $5.16 |
What do airlines gain from this expense??
Although it seems like an extra cost, indirect profitability is massive:
- Loyalty and NPS (Net Promoter Score): On 2026, the passenger is no longer just looking to "get there cheap", search for “get connected”. Starlink offers latencies of 20-40ms (similar to terrestrial fiber optics), allowing video calls and online games, something impossible with legacy antennas.
- Attraction of business travelers: A low-cost airline that guarantees high-speed WiFi becomes a viable option for the corporate passenger who needs to work during the flight.
- Operational efficiency: Low latency allows crew and aircraft systems to transmit maintenance and telemetry data in real time, optimizing scales and reducing delays.
This technical efficiency is what really triggered the final interaction. After demonstrating that its technology almost completely eliminates the excuse of spending on fuel, and given the resistance of airlines to modernize quickly, Elon Musk dropped the media bomb: He said he was interested in buying Ryanair.
If Musk managed to vertically integrate Europe's cheapest air transport with the world's most advanced satellite connectivity, I wouldn't just be selling flights, would be selling mobile offices to 30,000 feet tall.
