RTW question: itinerary allowed?

[Bitterroot]

Interesting. SIN-NRT/HKG-SFO is less of a backtrack than IAH-DME/LHR-SIN.

Yup.........but that appears to have nothing to do with the rule: "No backtracking is permitted except between two European points. This may be by surface or by SQ services."

So, he could add a few miles by flying JFK-FRA, surface to MUC, SQ MUC-MAN, then SQ either MAN-SIN or LHR-SIN, etc.

Good catch! So the route which maximizes mileage on SQ metal would be IAH-DME/MUC-MAN-SIN-NRT-LAX.
