It is very useful seeing the various RTW itineraries in the thread “post your rtw trip routing here” started a year ago which has recently been bumped. However, I’m particularly interested in the use of nested RTWs—or other complex combinations and would like to see how others have used them. It seems useful to break these out into a separate thread, which I propose to start here with the two RTWs that my wife and I will be beginning next week. They are as follows:

AONE4 ex-CAI (start)
A01:CAI-LHR (Week 0)
A02:LHR-CPT
A03:CPT-JNB
A04:JNB-SYD
A05:BNE-MEL
A06:MEL-AKL
A07:AKL-BNE
A08:CNS-PER (Week 12)

DONE4 ex-BKK (start)
D01:BKK-HKG (Week 13)
D02:HKG-YVR
D03:YVR-JFK
D04:JFK-DFW
D05 DFW-SJO
D06:SJO-LAX
D07:LAX-LHR
D08:LHR-DXB
D09 DXB-LHR
D10:LHR-FCO
D11:FCO-HKG
D12:HKG-AKL
D13:AKL-ADL
D14:ADL-PER
D15:PER-AYQ
D16:AYQ-SYD (Week 25)

AONE4 ex-CAI (resumed)
A09:SYD-JFK (Week 26)
A10:JFK-YVR
A11:YVR-DFW
A12 DFW-SJU
A13:SJU-DFW
A14 ;DFW-ANC
A15:ANC-DFW
A16 ;DFW-YVR (paid extra)
A17:YVR-LHR
A18:LHR-IST
A19:IST-BCN
A20:BCN-CAI (Week 50)

DONE4 ex-BKK (resumed)
D17:SYD-HKG (Week 62)
D18:HKG- DPS
D19 DPS-HKG
D20:HKG-BKK (Week 64)

The trip is based on flying to destinations that we need/want to go to, rather than mileage runs per se (with a few exceptions such as LHR-DXB-LHR).
The separate tickets that are necessary are, at the outset, from home in YVR, need YVR-CAI. Then between A08 and D01, need PER-BKK. Then between A20 and D17 need CAI-YVR and YVR-SYD. Plus there are a few other short surface segments.

At D20 we may start a new RTW from BKK—or possibly at A20 from CAI.

Starting from a base of zero FF credit in both AA and BA, by judicious assignment, it should yield, AA EXP by week 34 and BA Silver by week 24 and Silver renewal by week64 (with a short Club Europe RT thrown in to get enough BA metal).
