Elon Musk’s Starlink is rapidly expanding its presence in commercial aviation, with more airlines adopting the satellite provider’s high-speed in-flight WiFi service. Starlink says more than 1,400 commercial jets worldwide are now equipped with the technology.

More than 40 airlines have announced agreements involving Starlink WiFi, highlighting the growing competition in the in-flight connectivity market. The service is being promoted as an ultra-high-speed alternative to traditional aircraft internet systems.

Availability is not universal across every route or aircraft. Travelers may need to check whether their airline has a Starlink agreement and confirm if the specific plane operating their flight is equipped with the service.
