I've worked with Panasonic Avionics since early 2014 on a reskinnable mobile companion application to their airline infotainment seatback experience.
The iOS and Android applications are designed to pair with the passenger's seatback system, allowing them to find information about their flight and airline destinations, watch movies and TV, listen to music and radio, read news and magazines, and more. The system is designed to allow the user to control entertainment on their seatback or stream entertainment content directly to their personal device. The application functionality varies depending on whether the user is on the ground or on a supported plane. It is designed with flexibility in mind, making it easy to add and remove features and rebrand for additional airlines.
