Hailstone,
I think what arca-somebody is trying to say is that he gets 7 days off (aka G's) period.
That's not a lot if you, during most of those working days, don't get home at all.
Another problem is that the roster is very unstable and changes at short notice. You might be schuduled for a morning turn-around to MNL or TPE at 6 am and expect to get home in the early afternoon. So you make plans for the evening or late afternoon. But guess what....the day before they change it so you end up getting home at midnight and all your plans go down the drain. That's ok if it occurs once in a while but when it becomes the norm, then......you get pretty sick of it.
