Evan from F.A.T. figured out this air travel hack: put a big zip tie between to traytable supports to prevent seats from reclining. And to the poor dude sitting in front of Evan, don’t take it personally, it’s to fight unjust legroom cutbacks. I wonder if the two poeple sitting there next to each other could defy this trick by reclining together!
