Hi,
I am planning a RTW for next year and although I have a OTA at hand who claims they have experience with that I would like to inquire the collected wisdom of the forum for my intended routing.
I "think" it is a valid one however during a brief preliminary discussion with OTA she had some doubts about it.

So far it would look like this:
OSL - DOH - CMB - CGK
CGK - HKG - CTS
CTS - HND
HND - DFW
DFW - ANC
ANC - LAX
LAX - JFK - MAD - AGP
AGP - HEL - OSL

Real stopovers would be CGK, CTS, TYO, DTW, ANC, LAX and potentially AGP, others should all be possible as connections (less than 24 h according to my checks).

a) Is that a valid routing?
b) OTA seemed to be confused about the backtracking within USA to ANC but I think that should be allowed if I remember correctly?
c) Tbh, the only thing I am not so sure about is the end, if this MAD-AGP-HEL-OSL is permitted

So if anyone has any input it would be greatly appreciated

PS: Not sure if this is the correct thread, so feel free to move
