Ok lets clear my understanding. Maybe I am splitting hairs here,"the guys that went through the hiring process"......two ways, premerger DELTA, pilots went through the entire interview process in its totallity from XJ and were hired by Delta. The flows had no testing, interview or psych exam to fail, just a checklist of extreme items were covered like felonies, no degree....but there was no "hiring process" So you say the guys Delta had no choice in the matter to take "flows" were the jerks? or " the pilots that went through the hiring process that Delta?
Yes there is a difference, one where personality was checked by a three panel Delta team and one where there was not. Again it doesn't mean its a perfect process but this is where airlines filter, at their best, the personalities they prefer.

Before anyone has a tizzy, I have no problem with the flow at all but there is a massive difference between making it through the entire Delta hiring process and flowing over. I'm not condemning one or the other, they are just apples and oranges.

Also I know many of the flows and most were good pilots and nice to fly with. There has been only a couple I wish never would have come over. That's the case everywhere though. Most of the past flows are great guys IMO.
