OK tweaked the route a bit now got SYD - NRT & NRT - BKK. Thought MEX - LIM would not be allowed due to backtracking back NA to change at either MIA or DFW. Still got a problem with europe but may just drop FCO & leave it as CAI - MAN.

MAN – JFK
JFK – MIA
MIA – MEX
MEX – LIM (via MIA orDFW)
Overland to SCL
SCL – IPC
IPC – SCL
SCL - AKL
AKL – SYD
SYD – NRT
NRT – BKK (via HKG)
BKK – CAI (via HEL & LHR)
CAI – FCO (via LHR)
FCO - MAN
