All,

I am considering ticketing a RTW fare with Star Alliance, from NRT with SQ, in the next few days. I am familiar with the Oneworld fares (indeed, I am currently on one such journey), but not those of Star.
I have checked this itinerary with the mileage calculator, but would appreciate some opinions. The real purpose of the trip is the HKG-xSIN-LHR leg, with the rest simply as fun. In particular, I want to maximise:

(1) Travelling in first class
(2) Travelling on SQ (to retain my PPS).

Here is the proposed itinerary:

NRT-SIN-HKG-xSIN-LHR-FRA-JFK-SFO-SIN-NRT

According to the calculator, this is 31886 miles and hence FRWSTAR2. I am tempted to make my own way from JFK-SFO, but I gather the miles of any surface segment are included in any case.

I would appreciate any advice on how to improve this, or anything I am overlooking.

Thanks in advance,

Irish lad.
