United js nrt-sea

[MTNHI]

Is there a JS available on this flight? (NRT-SEA) Flt time is just over 8 hours so there is going to be at least 3 pilots. But is there a 4 pilot or not? And if not are all the 777's for UAL equipped with a 2nd JS? I would assume so but I thought the same on a UAL 757 and come to find out there is only one JS on the 757.

Thanks for any help.
