JSX's In-Flight WiFi Provider
JSX exclusively uses Starlink, a low-Earth orbit satellite network, across its entire fleet of ATR 42-600 and Embraer jets. This partnership, established in 2023, made JSX the first air carrier to adopt Starlink for in-flight internet. The service has been fully installed on all active aircraft since May 2023, ensuring consistent connectivity on every flight.
Expected WiFi Speed and Performance
Passengers can expect high-speed, low-latency internet connectivity with Starlink on JSX flights. Typical download speeds range from 100 to 350 Mbps per aircraft, with reported in-flight averages around 234 Mbps and peaks up to 424 Mbps. Latency is notably low, often between 30 and 60 milliseconds, making it suitable for activities requiring quick responses.
What to Expect Onboard
The Starlink WiFi service on JSX is designed for ease of use, offering an "instant on" experience. Passengers simply select the "Free JSX Starlink WiFi" network on their device to connect, without any login pages, credit card requirements, or loyalty program sign-ups.
