Reply to comment by epic1107 in eli5: Why do most airlines still use 2-pin audio jacks for the in-flight entertainment systems on their planes? by JJGLC92

I fly a little more than you, mostly US domestic, mostly Delta. Had no idea what this post was about, only ever seen 3.5mm jacks. So yeah, maybe its a regional thing.
