comments Elon Musk and Ryanair CEO Michael O'Leary have exchanged sharp words after the airline boss confirmed he has no plans to introduce Starlink internet on board the carrier's aircraft. The dispute began on Wednesday (January 14), when O'Leary dismissed the idea of installing in-flight Wi-Fi across Ryanair’s fleet, expressing concerns over increased fuel consumption. His comments prompted an immediate response from Starlink, the satellite internet service owned by Musk. Speaking to Reuters, O'Leary said fitting an antenna to the aircraft fuselage would add both weight and drag, resulting in what he described as a 'two per cent fuel penalty'. He added that Ryanair's passengers would be unlikely to pay extra for Wi-Fi on short, one-hour flights, reports The Independent. Ryanair operates thousands of short- and medium-haul services across Europe, North Africa and the Middle East, and currently offers no on-board Wi-Fi to customers. Starlink, developed by SpaceX, delivers high-speed internet through a vast network of low-Earth orbit satellites. In response to O'Leary's remarks, SpaceX's vice-president of Starlink engineering, Michael Nicolls, took to X.

Musk then weighed in on the matter, also taking to X to criticise the Ryanair boss. He called O'Leary 'misinformed' and warned that Ryanair would lose customers to airlines offering internet access. In another post, Musk labelled the chief executive an 'idiot', writing: 'Ryanair CEO is an utter idiot. Fire him.' O'Leary responded the following day (January 15) during an interview on Irish radio station Newstalk, where he said installing Starlink would cost the airline between $200 million and $250 million annually. He said: ' In other words, about an extra dollar for every passenger we fly, and the reality for us is we can't afford those costs. 'Passengers won't pay for internet usage; if it's free, they'll use it - but they won't pay one euro each to use the internet.' The Ryanair boss also hit back at Musk directly, telling listeners they should 'pay no attention whatsoever to Elon Musk'.
