Thanx skid...
I think he answered 1, 2 and 3 pretty well. One thing on your first question, Comair wants you to finish training, and will go out of their way to help you meen the standards, which is indicitive of the rest of the company. However its ultimately up to you to meet the standards. Since you're concerned enough to ask the question, I don't forsee any problems for you. As for question 4, I was jr. manned. You'll usually find me at the bottom of a seniority list, and you will now on the 70 seat list.
How it happened? They opened a bid and all of the pilots who wanted to go to the 70 seater were allowed to bid for it. If they're looking for 20 pilots and 21 want it, the most jr. pilot in the 21 doesn't get it. If they're looking for 20 pilots and 19 want it, they'll open a secondary bid. If they don't get somebody to fill that 20th spot, they'll look to the most jr. man available (finished IOE and no freezes, etc.) and force him in, hence "jr. manning". Well that happened and there were about 6 or 7 spots open, which means they jr. manned 6 or 7 of us (can't remember off the top of my head). The real crapper is that if anyone with higher seniority (earlier hire date) wants to go to the 70 seater, they slip in above us, so movement is rather slow, if there's any at all for us.
So in a nutshell, thats jr. manning, and thats how it happened to me. Thats my story and I'm sticking to it.
