Dude, I wrote up so many Compass planes you wouldn't believe over them having uncontrollable cabin temp, and plenty of squawks there such as flight control no dispatches that had been written up 11 or 12 times. It was not common but also not that rare to come across a plane that had been written up 9, 10, 11 times for the same issue. Many times an MEL would be applied, "fixed, ops checks good", next day back on MEL, oh look another 10 days or 90 days... Feds did nothing. Absolutely nothing. And once you'd write it up, it's not like you had any control over what they did because almost everything was a plane swap since surprise, things were breaking all over the place and any kind of long term planning was impossible. I did refuse an airplane once for uncontrollable cabin temp based on a huge number of writeups, an MEL for pack 2 and my FA saying she had been on that plane the day before and it was hot as balls in the back and popsicle town up front. That was fun. But rarely did you get to go into it with that much evidence.
And the problem with "going to a good regional" is that they don't always stay good (or bad, look at what's happened at Endeavor since they've been purchased). Compass MX was farrr better when I started before TSH really got their grubby hands up into things. When I finally left, it was embarrassing and sad.
