Rich,
The roster we get each month depends solely on luck. Some crew can get up to 16 days off and standbys a month, with maybe only 2 layovers and many turnaround flights. While some others get 2-3 EU flights each month with a mixture of Asian flights and zero turnarounds.
From what I know, crew and pilots from QR are resigning to join Etihad mainly because of a better pay. Needless to say, Abu Dhabi is more liberal as well. If you love pork and want to be with a company that does not intrude your personal life, Etihad would be a better choice.
If you don't mind doing without pork, staying at home nearly 24/7, and love wearing bright red lipstick and red uniform, scrunchie etc, I welcome you to our Qr family, where everybody is joining and resigning at the same time.
