Could either be a Dreamtime or Millennium configured 767-300. Domestically there are more aircraft changes which makes it harder to predict. Domestically it's harder to determine what plane you'll get, unlike when you fly international.
Only way is to actually walk up to the aircraft and check registration before boarding.
Ok, I finally have to ask the question. Can someone give a brief description of the difference in the Dreamtime and Millennium seats in J, I have flown in many differnt J seats on Qantas but have no idea which is which
Reggie, millenium seats are the standard domestic business seats.
Dreamtime seats are the old international seats that pop up occasionally on domestic legs (now that many of the 767s that used to be international, are now being used domestically).
Dreamtime seats, are in my opinion, much better. Better recline, more comfortable and more leg room.
