I'm in a similar situation, sort of. I am buying a LONE5 ticket originating in Ecuador. When I talked to AA RTW desk yesterday, the person I spoke with insisted that to get the Ecuador ticket price ($3900 vs. $5100 USD buying in the US) I had to physically purchase the ticket in Ecuador. I'm new to this, but that didn't seem right to me so I tried to ask in different ways of how I could do this over the phone. She was pretty insistent that I had to buy it at an AA ticket counter in Ecuador, and she wasn't interested in figuring out any other way to do it. She almost acted as if I was "cheating the system" by doing it this way, instead of paying the US price.

So... I agree that they might be quoting you the Canadian price. If it happens again, maybe tell them you want to purchase the ticket in Jordan!?

Regarding the online tool... when I first started using it (2-3 weeks ago), I also couldn't get anywhere with the "Book Now" button. But for some reason within the last week it's started working for me. I've changed my itinerary a bunch so maybe it has something to do with that.

At this point I could buy my ticket online with the OW tool. But I'm a little hesitant, because I want to see what price AA comes up with after taxes to compare it to the online tool results. Maybe it'll be the same price, but I really have no idea, and I'd like to go with whatever is cheaper. Also I'm pretty sure if I book online it will be with LAN, but it sounds like AA is easier to contact during the trip for making changes (although I'm starting to doubt their customer service in light of our current problems booking tickets).

Anyway, I'm not sure this helps you at all, just another data point.
