Sometimes they bring it up. I caught a ride on them a few years ago. I went to the flight deck and said "how's it going?" (as in hello, how are you today?) and got an earful on how two diffent pilot groups, working for one airline, were being paid two different rates to fly the same airplane, The guy with higher rate has only been here XX years, etc. Next time I ride on them, I guess I'll just stick with a simple "hello."

Once the rant was over, the captain was very accomadating, and I was welcomed aboard. The FA's have even bumped myself and my wife to first a few times. Proceedures for express are the same.
