A shift from single-provider inflight connectivity towards multi-network aircraft systems is taking shape, with Airbus and the Seamless Air Alliance exploring how airlines could select among satellite links based on cost, performance and operational needs. The options under discussion include networks from Amazon Leo, Telesat, SES, OneWeb and China’s Spacesail. The concepts remain prospective: no new airline deployment or finalized routing model has been announced.
Airbus is developing HBCplus modular, planned to enter service in 2028, with a design intended to support multiple providers and satellite orbits. The system is expected to accommodate up to two antennas, including electronically steered antennas, and allow airlines to change network configurations without replacing the full installation. Current HBCplus offerings already support access through multiple service providers and orbits.
Quvia aviation executive Mike Moeller described a possible model in which aircraft maintain several active links and route traffic according to application requirements, passenger experience, network performance and price. Satcom specialist Peter Lemme outlined a longer-term concept for dissimilar cabin connectivity systems to support operational resilience, while characterising it as a five-to-10-year prospect rather than an imminent change.
The Seamless Air Alliance is seeking airline input on connectivity uses beyond passenger Wi-Fi, including electronic flight bags, datalink communications, maintenance workflows and ground links. Industry standards work also covers antenna configurations and multi-beam electronically steered antennas, alongside efforts to simplify passenger Wi-Fi access and use mobile-network capabilities for identity and security. Greater use of connectivity in flight operations would increase the need to consider reliability as well as bandwidth and cost.
