to 330 man
As you mentioned, people started resigning from the 320 training, at least one I know, and the others are waiting for few weeks to see if the MFF to the 330 will ever happen or is it just another management promise.
I tell the 320 guys the MFF is not the answer for your career, you will stay on the 320 forever while you are just keeping the 330 current on your license by flying the minimum requried hours on type. That is not a real change in your life style.
