Maybe the passenger was a CO refugee who got asylum at AA before heading to greener pastures at DL to practice using school-era skills of changing the channels on the TV and/or cable box using his feet?

I am pretty sure that it wasn’t that guy’s first and only flight doing this kind of thing, and I’m certain some others have done this kind of thing on planes before. The upside of economy class seats that aren’t in the bulkhead is that there just aren’t that many men in their 50s able to do this kind of thing when seated in most economy class seats.
