I replicated a Qantas flight from YMML (MEL) to Antarctica and back in the Captain Sim 767-200. I know Qantas used a 747-400/400ER for the flight, but my "other" 747-400 wouldn't do the distance (I probably messed up the planning), so I selected the long range of the 767-200 for the trip. I did this in late 2009 or early 2010, long before Antarctica X was released. I took quite a lot of screenshots of the flight over and around Antarctica, but the default scenery was pretty boring to say the least. But it was a fun flight even back then.

I found the Qantas Antarctic flight plans online somewhere, but I no longer remember where.

I did plan to do the Air New Zealand flights too, but I couldn't find them. I was going to use the "other developers" DC-10 (ANZ livery), but I never flew that plane much. I even thought of trying them in the "other" MD-11 (also in the ANZ livery), but never got around to it.
