Well said Stick Pusher.
A little bird in DJ informs me that the lights are burning late in the Kremlin on that very question.
Evidently the 737 F/O's slated for command on the EJ may leave a severe experience gap in the right seats of the 737 operation. This has been hilighted by the problems some new and less experienced guys have been having adjusting to the operation.
Then there is the problem with the EJ EBA? What EBA? With the voting down of the new proposed DJ agreement, the introduction of the Embraer may be in trouble on 2 fronts, Operationally and Industrially!
