People claim to have it all figured out and the reality is that the your schedule is up to the company's needs and wants. No matter how you bid or how much you think you've got it figured out this "PBS" system barely follows seniority and is a way for the company to cover all of their flying at the expense of your quality of life. You can take all the tutorials you want, but no matter how you bid your schedule will still have numerous days that are awarded out if seniority. This CBI is the same pile of ****** solver, but it's in a fancy little package.
