Upon launching the new Polaris cabin last month currently the
SFO - SIN, and SFO-LHR city pairs are being flow on the B789L featuring the Polaris 2.0 cabin.
With more new planes joining the fleet additional destinations can be added, likely most out of SFO.

SFO-ZRH seems to begin in early September - given the strong premium market conditions in Switzerland.
Adding more LHR flights and 1 out of the 2 daily SFO-FRA flights are other possibilities.

Relaunch of LAX-SIN has been discussed in LAX threads as well.
