Just phoned and checked on this.
All S class. So no SWU's possible.
LHR-LAX/SFO-SYD both run over 25,000 miles RT - most direct routes.
2P right there. 1P on the double EQM.
If they allow routing via NYC or IAD etc this of course will increase.
Starting from Scotland or Manchester (all on BD) adds 2 extra mile segments.
