So we now have a DEC on the 777 while at same time 40% of the 777 FOs are going on the Bigbus to become commanders because of zero 777 vacancies! And the bigbus FOs are going on the smallbus. And this particular gentleman is coming from his 737 direct to the left seat of a 777.
Ok folks welcome to ETIHAD the National mess of UAE. Bxxt over and accept it like a man. This is the only reasonable explanation you will ever get. It is not “their” fault. It is yours. It is yours because you knew from before that they will do it because they can. And they will do it again and again until you get used to it or until you are out.
I hate to say “you were warned” but it is true. Oh and don’t forget to show this gentleman how to fly the plane.
