I have one on my avoidance bid, but plenty of names are on my own personal list. The one I have is the number one HOU guy and he is well known by all parties. The only reason I keep him on there is because I assume someone is tracking this stuff and I want them to have the data point. I wouldn’t fly with him again, but that is easily accomplished via ELITT and ttga.
Life is too short to fly with miserable folks. I just had two trips in a row with delightful captains who made the whole affair go so well. I am done apologizing to others for the behavior of my flying partner and done being miserable on account of others.
