I don't have many regrets from my SkyWest experience, but there is one that stands out:

I called the PBS help line to learn how to use "bid avoid". I had worked there a couple years, and flown with many people, before wanting to use that feature. But one person really stood out in a bad way and it was clear I should not share a flight deck with them again. The person I spoke with was very helpful with the PBS issue, but also suggested that I make a call to professional standards (we did not get into specifics about my issue).

I didn't make that call, and I should have. Just something to consider after your bid avoid.... for the sake of everyone else in your seat.
