Yep. This is an interesting situation. Prior to the implementation of the "9/11 security fee" in the US, this was also the case for domestic US awards. The other fees, such as the federal excise tax and airport PFCs don't apply to award tickets, but the 9/11 security fee does. So when that was implemented, the situation of having an award ticket with $0 in taxes and fees went away for the most part. Apparently it's no longer something on the website's test plan. Domestic Japan award tickets are the only situation that I'm aware of where there are still $0 award tickets, although there may be others.
