This is absolutely so not true! I left MAS about a dozen years ago. Even then, most of my crew were taking home 3-5K. The most junior galley steward was hitting roughly 3K. Now this was on the 744. I doubt even the 734 would have been much less.
Sorry mate,not buyin that gag!
I am now with an airline where ex-MAS cabin crew have left a week after joining.
Reason:Low salary!
