If you’ve used an in-flight entertainment system, known in the airline industry as an “IFE,” to watch movies, listen to music, or order food lately, chances are it used Linux as an operating system. You might not know that Linux is the operating system behind what you see on your screen, but it probably is. United, Delta, Qantas, Emirates, Virgin America, Aeromexico, Air New Zealand and many other airlines all use versions of Linux-based IFE software.
