Hi Himeno, thanks for your help!

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.
Why do I get the local price regarding taxes & fees when using the online tool? My understanding is that when booking online, the booking goes to the airline which is carrier of the first flight (in my case that would be Cathay Pacific or Japan Airlines). Do you mean that I can influence the taxes/fee of the entire ONE ticket (not only of the first flight) by chosing the carrier of the first flight? Or is it possible with the online booking to give the booking of the ONE ticket to an airlines of my choice (even when its not the carrier of the first flight) and I have not discovered this option yet?
@deconz: thanks, nevertheless I got the feeling that there is still plenty of room for improvment
