Hajj Man,
I flew with quite a few of the DEC's at EK, and most of them are good at what they are doing. All of them are great to fly with as they are relatively new in the company and are still enjoying Dubai without moaning to much.. it's a change.

I think the DEC's are colleagues just like everybody else and they are not to blame for taking an opportunity that was given to them by EK, even if they lack experience compared to some F/Os who have been kept waiting longer then expected.
I do understand that one is completely pissed of hearing the DEC he's flying with has his first job on glass or with pax at EK, but they only applied for a better living themselves..
I have no idea about your situation at QR, but don't blame your DEC's.
For the EK guys..
As a F/O at EK, we're completely f

cked... EK management can do whatever they want with us.. most of us can't leave... Bond, car loan, expenses of moving again, trying to find a better job then EK (no, I'm not planning to go back to some Low Cost just because of that left seat). Combined with all the saving you can do as a F/O at EK (nada), our situation is just asking to be exploited... sad but true..
