JSX Starlink WiFi — Free on Every Flight

JSX is the most thoroughly Starlink-equipped airline in the United States. The Texas-based hop-on jet service announced its Starlink partnership in December 2023, and at roughly 75 of 80 aircraft equipped — a 94% coverage rate — its rollout is effectively complete. JSX operates under a public charter model out of private FBO terminals rather than commercial airport gates, which means passengers go from kerb to seat in around twenty minutes; layering Starlink onto that already-differentiated product has made JSX the de facto reference standard for in-flight WiFi quality in North America. The fleet is small and homogeneous, which is part of why coverage moved so quickly. JSX flies the Embraer ERJ-145, the smaller ERJ-135 and a handful of ATR 42-600s on selected routes. The database currently tracks 36 of 37 ERJ-145s as equipped, all 14 ERJ-135s, and all three ATR 42-600s — the remaining unequipped airframes are typically newly-delivered or in maintenance rotation. Because the aircraft are configured for 30 seats rather than the 50 the airframe is certified for, the antenna-to-passenger bandwidth ratio is higher than on almost any other commercial flight, which is the technical reason JSX consistently posts the fastest reported in-flight speeds. For passengers, Starlink is free, requires no purchase or sign-up flow, and is available to everyone on board. There is no cabin segmentation — JSX is single-class — so the connection is universal. Reported speeds frequently land in the 50 to 150 Mbps range per device, fast enough for video conferencing, high-definition streaming and large file uploads at altitude. The Starlink fitment is visible as a small rectangular panel on the aft fuselage.
