Hi all, I'm a semi-regular lurker, first-time poster. Thanks to the community for the wealth of information buried within the forums!

My wife and I are planning a LONE4 for our honeymoon from January to Mayish, and I'm feeling a little overwhelmed. I've already booked award tickets to Japan so we can take advantage of the cheaper RTW fare. Our ideal itinerary is KIX-BKK-SIN-MEL-AKL-SCL-IPC-EZE-UIO-LIM-MAD-IST-CPH-HEL-NRT with some side trips thrown in. All of those seem to be direct flights except for the IPC-EZE leg and IST-CPH. If I do a surface sector from UIO-LIM, will this be a valid itinerary? Or will I be at 17 segments?

The online booking tool doesn't offer me any direct flights for AKL-SCL, but the route map seems to show a LAN flight. Does that mean there's no availability on my dates? Or is it a quirk of the tool?

Are there ways we can be wringing more miles out of our itinerary?

Will I be able to book through AA even though none of my flights are operated by American?

And finally, this question is a little more free form, but does it make sense to look into a DONE3 instead? By which I mean will the extra miles we accrue by flying business class allow us to book travel to the 4th continent that will get left off the itinerary?

Thanks in advance for any and all advice!
