Ive only had a few isolated incidents where DL gate agents or other pilots have f'ed up my commute. The vast majority of the time, they are as helpful as can be, especially the DL pilots that have offered to ride the FA jumpseat to try and get me in the cockpit (usually FO's, but they are the ones closer in boarding priority to me anyway). And all the crews that have welcomed me on the jumpseat (again, usually the more junior they are, the more welcoming) are the heroes in my little commuting drama. I will do everything I can to get folks on board.
Not me. I don't commute so F them!
