Rossma,
I'm with you 100%. I think it was very derelict of the crew not to advise you pax of their intentions shortly after establishing themselves on course for the UK. It looks like they set course for home well before crossing the California coast after completing their second circuit over the Pacific. As you passed Victorville, which lies some 75 mi as the crow flies NE from LAX, right behind you on the same course and at the same altitude, was a Virgin A340 out of LAX (I shouldn't say ex-LAX) headed for LHR. From Victorville it's another 170 mi or so to Las Vegas.
