Decided to scrap DXB and MLE, and do the following

MME-LHR-NRT (BD-NH)
NRT-HKG (NH)
HKG-SIN (SQ)
SIN-SYD (SQ)
SYD-CHC (NZ)
CHC-WLG (NZ)
WLG-AKL (NZ)
AKL-HNL (NZ)
HNL-LAX (UA)
LAX-LAS (UA)
LAS-ORD-LGA (UA.TED-UA)
LGA-BOS (US)
BOS-YYZ (AC)
YYZ-MAN (BD)

Total: 28828 miles

Anyone spot any problems with this routing?

Anyone any opinions on the LHR-NRT with NH?
