One thing I've been meaning to broach since I reissued my DONE4 in AMS with BA, is that the airline restrictions changed. My original BKK issued ticket had the usual list of allowed carriers, BA/CX/QF/AA etc. My reissued ticket in AMS showed however "Valid oneworld carriers only," and my re-reissued ticket by QF in SYD still shows the same restriction. (It also changed to an e-ticket.)

So, my thought is this: the new wording potentially allows the use of new carriers like MA, RJ and JL once they join oneworld. Of course, that would require another reissue and it's probably not worth it in this case, especially since my ticket expires 18th of April. Perhaps this is something to look out for on your tickets.
