So just had a win! Called back as got email from qantas about my seat release request. Long story short the previous agent had got my departing & arrival city around the wrong way, which mind you was approved. Anyway new agent I spoke to was excellent from premium call centre (team leader doing overtime). I had a couple of legs on rtw reward booking to finalise + itinerary had to be split. Worked with me & got 4 x J released end of Jan from HKG to Syd was originally going Bangkok - tokyo - sydney economy & another 2 x J HkG to Syd in July released for a return from Europe. Couldn't speak more highly of the agent, When it works it's fantastic! BTW I've been platinum for 36hrs, making it work hard..
