Gogo Avance L5 and AVANCE SCS: the dominant US air-to-ground connectivity system, with continental US and southern Canada coverage. Latency is low; throughput is sufficient for video calls and streaming. Coverage ends at the coastlines.
Jet ConneX (Inmarsat Ka-band): the standard global satellite system on heavy and ultra-long-range jets. Coverage is genuinely worldwide; throughput supports concurrent video, large file transfers and multiple users.
Viasat Ka-band: a third premium global satellite option, increasingly fitted on Globals, Falcons and Gulfstreams. Operationally comparable to Jet ConneX with slightly higher peak throughput.
Starlink Aviation: the newest entrant, currently being certified across major business jet types. Where available, latency and throughput are materially better than legacy satellite systems.
Practical reality: cabin video calls work reliably on Jet ConneX, Viasat and Starlink. Gogo Avance is sufficient inside continental US. Older systems (Aircell Axxess, SwiftBroadband) struggle with video — confirm system version before charter if connectivity matters.
