Definitely not an L-UAL thing. Did quite a bit of international jumpseating on them before the merger and they were always my carrier of choice as I never rode less than biz (very grateful for that, thank you!). Later found out it was policy to sit J/S's in J class on international flights, very classy I thought. It's a shame that hasn't seemed to transfer over to the new UAL. Don't get me wrong, when riding the "jumpseat" I/we are all always very happy for any seat! But, let's not kid ourselves it really is nice when you have a bit of extra room on the long flights.
