Actually, I have heard that there is NO short course...please someone with contacts somewhere, let us know...because I keep hearing both yes and no on that front.
As for 744 new-hires? Be patient, grasshopper...your turn will come soon. I realize the waiting is frustrating, especially when you consider that you are in the hiring pool having met all the requirements, and others come along and grab a 767 class...therefore, gaining seniority numbers on you. I'm not sure there is a solution for that...
Good luck...and best wishes.
