That plane wouldn't have a contrail dropping down toward the western horizon. It's high enough, but may be at too high an angle to be in the view of the available images, or it may be in an area of the atmosphere too dry for creation of contrails.
I may have missed something, but I don't see any other planes coming in from the direction of Hawaii above 30,000 feet.
UPS902 was on the same exact route just minutes apart from AWE808
