I'm going to be taking a RTW starting in November. Here's the basic itinerary:

CHC-ZQN
ZQN-AKL
AKL-SYD
SYD-BKK

Overland to Hanoi

HAN-HKG
HKG-JNB
JNB-NBO
NBO-LHR
LHR-CAI

Overland to Jordan

AMM-LHR
LGW-DFW
DFW-LAS
LAS-HOU

HOU-somewhere in the Carribean...haven't looked yet to see what's available.
Back to HOU

There will be ticketed LAX-AKL but it will be thrown away.

Any problems with this itinerary?
