Curious. I see more and more of the in-flight entertainment systems including USB chargers on them - for charging, not listening. My experience on flights where I use the analog jack is that it's usually a terrible experience, in terms of audio quality. IFF the USC-C standard becomes more ubiquitous, this might be rendered a moot point. Of course, I do not know if the USB-C has been tested for the kind of brutal, constant usage that would be common on aircraft so I might be completely wrong.
