i have a question, since psa and pdt are cheaper now or appear to be then why is aag sending embraers to tsa and ejt. granted psa is slated for middle next year to start receive the crj's at envoy, but pdt is starting the embraer 145 program, and the tsa/ejt aircraft are not until mid 2015 to 2016, so i ask why are they not going to pdt? Mostly all aircraft that are to leave envoy hands are not until mid 2015, why this long?
