It is still remarkable when you board a flight, after trying to squeeze a few final minutes out of the airport WiFi connection, when you see that your aircraft has its own internet connection. Although the technology to connect an aircraft to wireless internet-providing satellites has been around for the best part of the last ten years, the global fleet rollout is less than half of global seat capacity, yet the in-flight connectivity market is set to increase from US$1.5bn in 2020 to over US$5bn by 2027. However, evolving technology is taking the concept of a ‘connected aircraft’ further and deeper than simply allowing passengers to scroll through their Instagram feed at 35,000 feet.
