Wi-Fi (Ka / Ku band)
Inflight internet on business jets comes in tiers. Air-to-ground systems such as Gogo work only over the continental US and parts of Europe at modest speeds. Satellite systems using Ku-band or, better, Ka-band (Viasat, Inmarsat Jet ConneX) offer 15–50 Mbps worldwide except near the poles, enough for video calls and streaming, and are standard on large-cabin and ultra-long-range aircraft. Low-earth-orbit services from Starlink are now being installed on everything from Citations to Globals, delivering 100 Mbps or more with lower latency. Data on satellite systems is expensive; some operators include it, others charge $5–$15 per megabyte or a flat fee per flight, so ask.
