The Basic with EY is much more, but the flight allowance is less.
All together at the end of the month don't think there is that much difference...between EY and QR (only when you go on leave as the basic is higher with EY).
People who are leaving QR for EY it's not for the money,but the way you are treated there i guess it's a world of difference with QR.
And Abu dhabi is probably a better place to live as well compared to Doha....
