So stuff like SFO-Europe, SFO-AKL, and even SFO-TPE will all be in range of this aircraft. SFO-BNE definitely is going to a 789 and maybe another frequency during the off-season and peak season, UA could always fly the 77W on it. We'll see what happens with SFO-SYD as this could be one of the routes where we see the High 789 and UA could fly this with more than daily service in the off-season and double daily during peak season, along LAX-SYD switching to this plane as well as IAH-SYD, and IAH-SYD possibly going year-round, albeit less than daily. The High J 789 with the increased MTOW is supposed to excel the most on a route like SFO/LAX-SYD, being able to carry a lot more cargo than previous iterations.
