It will take 100x the effort of dealing with AA. I tried once, and after the first hour hadn't managed to get LAN to understand that I was trying to buy a OWE product; gave up at that point. Perhaps there is a RTW specialist person at LAN, but I never found them.
LAN is at least moderately confused - as I've mentioned a couple of times, it took half an hour on the phone with res to book a AKL-SYD segment - ten minutes to convince the agent that her airline actually flew the segment, and the rest for her and her supervisor to figure out how to book it. (How can it not be visible in their own CRS when I could see it in EF?)
