US budget airline JetBlue will introduce Amazon low-orbit satellite network "Project Kuiper" starting 2027 -- upgrading its existing free in-flight WiFi service "Fly-Fi" so passengers can enjoy uninterrupted streaming and remote work from 35,000 feet altitude. This is the first case of an airline commercially deploying the Kuiper satellite network. JetBlue has offered free in-flight WiFi since 2013, but existing satellite internet relies on high-altitude geostationary orbit (GEO) satellites causing long latency and speed degradation when passengers crowd together. Under the new agreement, JetBlue will equip some aircraft with Project Kuiper low-orbit satellite communication equipment from 2027. Low-orbit satellites operate at 590-630km altitude -- much lower than GEO satellites, dramatically reducing data transmission latency and improving connection speed and stability. JetBlue President Marty St. George expressed confidence passengers will be able to freely enjoy streaming, work, and social media from altitude. The Kuiper competitive context: Starlink (SpaceX) has established itself as the dominant in-flight connectivity provider, already deployed on Alaska Airlines, Hawaiian Airlines, and others; Kuiper is launching its commercial service several years behind Starlink; the JetBlue partnership gives Kuiper its first major airline showcase -- a critical reference customer for gaining additional airline deals; for JetBlue, differentiating on WiFi quality is a meaningful competitive advantage in a market where fare differences between airlines are often minimal.
