I went to Australia twice once in 1999 and 2001 and both time I took the same plane but I do not know the model... on my recent trip last year to Australia I was on one of their domestic flights and it was exactly the same plane...It is that kind of sense of familiarity...The interior is rather sparse with only one big screen in the front and on the arm rest there is a led display with just 2 digits informing you of the radio station you are tuned to...
it has a seating configuration of 2-3-2 and it belongs to quantas...It has only two engines...
Thanks
