SES Secures Boeing Line-Fit Milestone for Multi-Orbit Antenna with JAL Deal

Satellite operator SES has reached a significant milestone with Boeing to offer its multi-orbit In-Flight Connectivity (IFC) system as a factory-installed option. The company also announced a major agreement with Japan Airlines (JAL) to equip 41 of the carrier's widebody aircraft with its advanced Electronically Steered Antenna (ESA) technology, with line-fit deliveries scheduled to begin in 2028.

This development marks a critical step in streamlining the installation of next-generation satellite internet on commercial aircraft. By securing line-fit offerability, SES and Boeing can integrate the complex hardware during the manufacturing process, eliminating the costly downtime and logistical challenges associated with post-delivery retrofits. For airlines, this means newer aircraft can enter service with high-performance connectivity from day one, enhancing the passenger experience and operational efficiency.

Agreement Details and Fleet Impact

Under the terms of the new agreement, Japan Airlines will install the SES multi-orbit ESA on 20 Airbus A350-900 aircraft and 10 Boeing 787-9 aircraft as a factory line-fit. Additionally, JAL will retrofit 11 existing Boeing 787-9 aircraft with the same system. The retrofit portion will require a Supplemental Type Certificate (STC), a regulatory approval for modifying an aircraft from its original certified design.

The system leverages both Low Earth Orbit (LEO) satellites for low-latency performance and Geostationary Earth Orbit (GEO) satellites for high-throughput capacity and redundancy. This hybrid approach is designed to provide a consistent, high-speed connection for passengers across JAL's extensive long-haul network. According to an SES press release, the company has completed over 500 installations of its ESA system to date and has commitments for another 1,000.

SES executives highlighted the importance of the Boeing milestone. "This is a testament to the quality and maturity of our multi-orbit solution," said Mike DeMarco of SES. Boeing's Destry Lucas added that the manufacturer is committed to bringing scalable, line-fit capable solutions directly into its production environment.

Industry Impact and Competition

The move significantly impacts several key stakeholders. For Japan Airlines, the upgrade to multi-orbit IFC on 41 long-haul aircraft represents a major enhancement to its competitive position, directly improving the passenger experience. For SES, securing a flagship customer like JAL and achieving a line-fit milestone with Boeing validates its multi-orbit strategy against LEO-only competitors. Boeing Commercial Airplanes enhances the appeal of its aircraft by offering factory-installed, next-generation connectivity, a key selling point for airlines.

This development also intensifies the competitive landscape for satellite operators. In April 2026, competitor Viasat began the qualification process for its own multi-orbit ESA to become a line-fit option on Boeing aircraft, targeting a 2028 entry. This parallels SES's push, demonstrating a clear industry trend toward factory integration. Previously, airlines like Hawaiian and United opted for post-delivery STC retrofits to install Starlink's LEO-only antennas, an approach that SES and Boeing are now aiming to bypass.

Technical Analysis

This development indicates a pivotal shift in the IFC market, moving from a primarily aftermarket, retrofit-focused industry to one where high-performance connectivity is an integral part of aircraft manufacturing. The pursuit of line-fit offerability by major satellite operators like SES and Viasat underscores the airline industry's demand for reduced downtime and guaranteed performance upon delivery. The technical decision to pursue multi-orbit (LEO+GEO) solutions by legacy providers contrasts with the LEO-only approach of newer entrants like Starlink. SES's success with Boeing suggests that manufacturers and major airlines currently place a premium on the network redundancy and high-capacity broadcast capabilities offered by GEO satellites, which complement the low-latency benefits of LEO constellations.

What Comes Next

The timeline for Japan Airlines' fleet upgrade is now established. SES is scheduled to begin ESA deliveries for JAL's previously ordered Boeing 737-8 fleet in 2027. Following that, the newly announced line-fit deliveries for the Airbus A350-900 and Boeing 787-9 fleets are confirmed to begin in 2028.

Why This Matters

The collaboration between SES, Boeing, and Japan Airlines signals the maturation of multi-orbit IFC technology as a standard feature for new long-haul aircraft. It streamlines a previously cumbersome installation process, reduces costs for airlines, and ensures passengers have access to more reliable, high-speed internet. This move solidifies the trend toward integrated systems and intensifies competition among satellite providers to secure coveted factory installation slots with major airframers.
