You're treading on thin ice with your caustic remarks.
To my knowledge the EK selection process is geared towards pilots who are up for command. It seems quite reasonable that F/O's should be upset at direct entry captains taking the slots.
The direct entry captain thing is not new in Emirates. It happened in the 727, A310/A300,and now, in the 777 and 330/340.
It is been in the policies since day one, and the company used it as they needed.
I am not sure whether they save any money hiring and training a guy from outside. Ultimately, yes, they use their command experience, but we, the more experienced f/os, have to actually finish their training on the line, as unofficial "training f/os" ... for free :-)))
It is not a fair thing, but there isn't much one can do, other than whine.
