Abstract: Artificial intelligence (AI)-based in-flight assistants and associated systems, devices, and methods are disclosed herein. In some implementations, an in-flight entertainment and communication (IFEC) system provides an AI-based virtual assistant that a passenger can submit various requests or queries. For example, a passenger can ask the virtual assistant to generate an itinerary for their destination, edit documents stored on their personal laptop, order food or other items mid-flight, reach out to a crew member, check lavatory availability, and more. An AI model onboard the airplane can process these requests and generate responses in real-time, even if offline. The virtual assistant can be visually represented by an assistant graphical character on a display and talk to the passenger. Thus, the AI-based virtual assistant can provide an improved in-flight user experience compared to conventional IFEC systems.
