Tim mate, dont lie!
They are pretty irregular at the moment.
-400s all last week and today where as the next few flights will be -300s and -200s. We had Wunala last week
So accordingly, in the most recent timetables they have put EQV, so I dont know why someone said they are -300s.
But in all seriousness, they mainly use -400s at the moment but occaisionally throw in classics.
As for SAA, they have -200 midweek services, whilst on weekends they use SPs. -SPC has been used every saturday for the last month
2 or 3 years ago, Qantas had a once weekly MEL-JNB direct service and a once weekly SYD-JNB direct service, both using unmoderated aircraft. So its possible, but I'd hate to fly it, especially when you can stop in such a beautiful city like Perth.
Perth needs there 747s especially after BAs farewell.
