Just tried the tool for the first time. Here's the itin I was trying to book: CAI-LHR-DOH-CDG-DOH-SYD-NRT-DEL-NRT-CMB-NRT-BOS-LAX-MBJ-LAX-DOH-CAI. The only problem I had with the online tool is that it would only allow 15 segments. Said that my itin was invalid for too many segments. Removed the last one (DOH-CAI) and it was fine. (Since it's not until July, I assume that there will be schedule changes before I start, anyway.)

So I called AA RTW Desk and booked it there. Very nice and apparently knowledgeable agent; he validated it, was mildly amused that I'm flying so much with only one real stop (BOS). (I also have a >24 hour stop in Los Angeles, but barely, at 27 hours. Just enough time to have a day off and maybe do a little sightseeing.) Submitted to rate desk for faring, should be back in a day or two.

The recent rule change so that local ticket issue in country of origin is no longer required is a most welcome one. Makes the whole process much smoother. Unfortunately, this will undoubtedly cost Mindpearl some non-trivial amount of business, -- they were always both knowledgeable and pleasant to deal with.
