If you are in Australia, if it is conveniant you can also book it and have it ticketed in Australia at the higher of the Australia or UK/Swiss price. From Australia, the price is AUD9699 plus taxes
To make the booking, I would suggest making a call to the AA ATW desk and get the itinerary stored and they can then price and work out the taxes depending on where you wish to have it ticketed. Just call +1 800 247 3247 . When you want to pay and get the ticket issued just call the appropriate AA office and they will take your money and issue it
Do avoid using QF or BA for this since the fuel fines charged by them will be a lot higher than AA
