It makes Wizz the first European ultra-low-cost airline to use the technology, though the company did not say whether passengers would be charged to use it.
Starlink, owned by billionaire Mr Musk’s SpaceX aerospace company, uses thousands of satellites orbiting Earth.
Many other airlines have either offered the service on flights or announced plans to do so, including British Airways and Virgin Atlantic.
Ian Malin, chief commercial officer of Wizz Air, said: “Ultra low-cost travel has always been about making opportunities accessible to more people.
“In 2027, we’re taking that philosophy into the space era.
“Our customers shouldn’t have to choose between affordable fares and reliable internet onboard to stay connected to the people, work and moments that matter most.
“We’re proud to lead that change by collaborating with Starlink to bring maximum benefit to Wizz Air.”
In January, a row erupted between Mr Musk and Ryanair boss Michael O’Leary over whether Starlink could be used on the airline’s flights.
After Mr O’Leary said this was not feasible, Mr Musk called Mr O’Leary an “idiot” and “chimp”, and mused on X whether he should buy the airline.
Mr O’Leary claimed the “PR spat” had driven a two to three per cent increase in sales.
