She called me up to the podium and asked me if I was a "must ride". I said, "well, I'm positive spaced to training, so I guess so." She then went on a dissertation about how PS has various levels and if I wasn't Deadheading to protect a flight, she could bump me until the very last flight of the night. I then asked her how I was supposed to get adequate rest for an 4am sim if she had me arriving at midnight b/c I would never schedule that way on my own. She relented and eventually let me on. PS to training is booked as PS5 and DH is PS0, and I have no clue what PS1-4 are. She never mentioned the jumpseat. The whole thing was weird to me b/c after 10 years at a regional, Positive Space was simply that, regardless of the reason, but this is apparently how UAL does it. Declaring "must ride" and giving your supervisor's name seems to be the work around for this as was explained to me by some UAX guys in my class.
