My wife and I are travelling on a RTW 1st class from Cairo this spring. I'd like to ask for some ideas as to how to get some additional miles, but we intend to visit all of the places were going to, so it's not really a mileage run. I'm putting an "S" where we are stopping.

CAI - LHR
LHR - ORD S
ORD - HNL
HNL - OGG S
OGG - HNL
HNL - SYD S
SYD - PER S
PER - BNE S
BNE - HKG - NRT S (I'd rather fly Cathay 1st)
NRT - HKG S
HKG - JNB S
JNB - CPT S
CPT - HKG - SIN S
SIN - LHR S
LHR - ???
and finally LHR - CAI

Does this look OK? Also, I was wondering how I could maximize something else in Europe out of LHR?

Thanks in advance for your help.
