Negative, EK does this. Etihad you are paid per diem based off the region on the world that you are in, and it's credited to your next month's salary. Some pilots suggested this but ultimately it would only benefit a few.

Also depending on the layover, I also personally find it pointless to have the cash since many are short, the weather is bad, or i'm just too damn tired to venture out looking for cheap eats. Room service/hotel buffet and if you need cash there's almost always ATMs or change at the airport on arrival. Even this way I still have loads of cash from countries I go to so infrequently that I never get the chance to use it.

I believe 300 or so hired last year and will probably have that many or more again this year.
