Booking AA Flights - Use AA US or AA Aus?

[smckay]

For more expensive domestic fares, you can exempt two taxes on the domestic ticket if you also have an international ticket.

You have to purchase from a travel agent that knows how to do tax exemptions and they must be located outside of the US though, but in your example you could probably get rid of about 170 AUD in taxes.

AAARRRRGGGGHHHHHH all.ready.booked.
This flight was $200 AUD taxes.

But, we are staying 5 days in the US before checking out so hopefully we would not qualify for a tax exemption? (Even if we do qualify can you just say we won't to make me feel better )
