...almost back to the RTW trip that used to be possible with ANZ (LHR-LAX-AKL-HKG-LHR, or vv) which I did with them around 10 years ago.
Has there ever been a LHR (or LON in general) - CHC direct service previously? I believe SQ and EK are the only long-haul visitors (aside from NZ themselves) to South Island currently?
