It is happening where one seeks to start from NRT. My JPY 713,000 DONE3 was accepted by the oneworld site and then when American Airlines looked at the ticket request to issue it they determine for my credit card I am not resident in Japan and so they are "pricing department" repriced the ticket for the Hong Kong resident that I am, HKD 79,000, about 40% more. See my post "RTW trick from NRT over". I am presently looking for a Japan travel agent who will work with me on future ticket purchases.
