Amazon's low-Earth-orbit satellite project, Amazon Leo, recently unveiled the 'Leo Aviation Antenna,' specifically designed for commercial airliners and aiming to challenge SpaceX's Starlink aviation business in the in-flight Wi-Fi market. The antenna features a flat, low-profile design compatible with aircraft ranging from regional jets to wide-body planes. It claims to provide high-speed internet connectivity for passengers, with in-air download speeds of up to 1Gbps and upload speeds of up to 400Mbps. Amazon emphasizes its installation efficiency, stating that the antenna can be installed in a single day, whereas SpaceX's Aero Terminal typically requires 10 to 14 days. In terms of performance, the antenna system's bandwidth is shared across the entire aircraft, sufficient to support common connected applications such as gaming and video streaming. Starlink's aviation service has already been commercially deployed by several major airlines and has received positive reviews. Amazon Leo hopes to replicate this reputation, with its global business leader anticipating that passengers will actively choose flights equipped with Leo connectivity services in the future. Regarding aviation customer expansion, Starlink has already partnered with multiple airlines, while Delta Air Lines and JetBlue have signed on to adopt Amazon Leo's services. However, Leo's overall system is still in private testing, with approximately 240 satellites currently in orbit—insufficient for comprehensive coverage and stable connectivity. Due to delays in satellite launch schedules, Amazon has applied to the U.S. Federal Communications Commission for an extension of its deployment deadline. According to plans, Leo services are expected to officially launch commercially by mid-2026, by which time the number of in-orbit satellites is projected to reach around 700. Even so, the rollout of Leo's in-flight connectivity services will take time. Delta Air Lines will not fully enable Leo across its fleet until 2028, while JetBlue plans to introduce the service in 2027. Technologically, the aviation antenna incorporates some technologies from Leo Ultra's ground terminals, with the airborne version enhanced for aviation environments. It can withstand high-altitude cold, severe weather, and various physical stresses during flight, meeting the reliability requirements for long-term operation on the exterior of aircraft.
