I had LAX-SYD issued for next week. I called and started by asking if she sees availability EWR-LAX so she said yes (you have to start this way, if you give them first the other PNR they wont see the other leg available anymore) now tha she knows there are 4 seats for award I gave here the other PNR and I told here "the 4 seats you saw before to LAX I need to connect to this PNR" so I hear how she is typing and talking to her self "oh, this new system its not coming up here, let me open a new screen" and after 3 minutes it was sold in. But this is not done, the hard part is to get it reissued since we are in the other system but she worked on it and after 5 minutes all was good.
