Not sure where the figure of 500 hours for Eurofleet cabin crew might come from. I'm full time, do an average of 3 x 3 days trips a month, the rest there and backs, and my planned hours to end of Jan are 669.40. I know there are those who would bring the average down (the early MAN club for example), but equally, there are those who work more than me (those who do 8 sector 3 day, and 6 sector 2 day trips).
I know that doesn't add much to this debate, but just wanted to point this out.
