Noob question. Why do most pilot groups seem to really dislike PBS, and treat it like the Boogie Man?
PBS won't let you bid into conflict, which makes most lineholders 10 or more percent above on the year. It's only for lineholders though :/.
Pbs gives you this wide variety of schedules and most positive attitude people create reasons why "oh thats nice" and pilots need to feel theres a plan B which they can see in advance. If a pilot has an ability to plan ahead, even if there's nothing they can do, they can "feel good" or in control.
PBS will at some point bite you, line bidding gives you the impression "looks, that's all the flying out there, the job has to get done. While PBS is the same thing, pilots don't perceive it that way. PBS often does some math you find out 2months later has been screwing you, but "it's what you bid!" Because "it's your preference!". Once you fix that a pilot is usually better off.
So line bidding gets you more money, makes you feel more in control (stupid and wrong), and you're gonna feel stupid using pbs at some point and it's all your fault. Pilots want to believe theyre doctor-lawyer rocket-surgeonry, so that hurts the ego.
