The resultant fare must not be lower than from the country of sale.
If the ticket starts in Germany and you are buying it in the US, you pay the higher of the two, converted to USD (if required).
When this doesn't work, what advantages do I have with booking at the AA desk? Apparently a lot of people try to book with AA even if AA is only a minor carry on their itinerary.
People tend to book with AA to reduce the amount of taxes/fees (mostly fuel) paid on the ticket. Until a few weeks ago, people also went through the AA desk to set up the ticket for sale via an agent in Canada. The rule exemption which allowed that was removed.

If you want the local price and are not present in that country when buying, you need to use the online tool or find an agent in the country of departure willing to do an online electronic transaction.
I think they count singapore to Asia. Funnily enough, when I skip the whole Japan thing and fly FRA-SIN-SYD the price is basically the same despite me havein a ONE3 now instead of a ONE4 - so under these circumstances SIN counts as asia???
Yes, Singapore is part of Asia. As is Indonesia. Generally "South West Pacific" is Australia, New Zealand and Papua New Guinea. The other parts of "South West Pacific" don't have regular oneworld service.
