Rerouting changes to an in progress LONE4 ex-CAI
 

Hey guys,

I'm currently part way through enjoying a LONE4 (thanks to your help putting it together :D) with a routing of:

CAI-,AMM-BKK-NRT-KUL-MNL-,HKG-CNS-sSYD-AKL-LAX-JFK-MIA-UVF-LWG-sLHR-CAI

Bold showing the still to fly segments. I want to make some route changes so those segments remaining become instead:

SYD-CHC-sAKL-LAX-MBJ-,MIA-IAD-LHR-CAI

Have a few questions:
1. Does the changed route look valid? I've put it into the rtw.oneworld tool and it seems to check out
2. Is the $125 change fee just once for all changes. i.e. if I bundle up all the changes for both myself and partner, it should just be the one fee charged?
3. The tool no longer allows start/ending in CAI. Do you think that will cause any issues rerouting this?
4. Per the rules I understand I should be able to end by flying LHR-DXB instead of CAI. Is that correct?
5. In practice is it reasonably quick/easy to make a change like this? One quick phone call, or should I expect some back and forth and a few days wait?

Also, to check the validity I've constructed a 'fake' itinerary in the tool that mirrors my ticket as close as possible (given that I can't start/end CAI now) and then playing around with the final sectors. Is there a better way to do this, other than just interpreting the pdf rule sheet in my head? :)

Thanks pandaperth, clears up a lot :) Ticketed with RJ, hasn't been the easiest making changes so fingers crossed!

Another quick question, do you know if Turkey is considered part of the Middle East for the 'end anywhere in the Middle East' rule, or if it's considered Europe?Can't seem to find a definitive country list :)

I believe it is considered part of Europe
My belief is based on some wording that used to be in the rules (they were removed in Dec-2016):
