Best advice is to go with an open mind if you want and if its not working out for you hand in your 30days notice and V1 rotate out of there.
I don't recommend the 30 days notice (the expat contract notice is 3 months anyway).
The "standard" method is to get the money in your pocket (on whatever day that happens to be... it varies, since they RARELY pay on time) and then get on a plane and go home.
Then, and only then, do you advise Arik that you're not coming back. Giving any notice is almost guaranteed to not get your last pay. Yes, there are current managers at Arik that will promise to pay if you give notice. But of course, like everything Arik, I wouldn't believe it, because it will never be true all the time.
There is a long list of folks who left Arik and never saw all their money.
