I was waiting to get on an Eagle flight in Houston-Hobby once going to DFW. It was before I was hired at my airline so I was in plain clothes, and just chatting with another guy, who happen to live near me. He said flew down to Houston often, and had lots of miles and he liked taking Eagle and AA. Meanwhile a JetBlue E170 pulls into the gate next to us. Another guy talking to us, asks if the man ever rode on JetBlue or any carrier like that. He frowned and said he would never want to take a carrier like that, with their inexperienced pilots and all. This all while he's waiting to board a regional jet! (nothing against Eagle pilots)

So I'm sure he's not the only guy that thinks all DL and DL Connection are all DL pilots, and well Southwest, Airtran and JetBlue guys are the ones that "couldn't cut it" at the "majors."
