May I humbly say this... I am currently at a regional that transitioned from line bidding to Flica PBS years ago. Our PBS is the envy of the industry. We weren't for it initially, but we all love it after we gave it a chance. Please think about PBS as line bidding on a WEEKLY (not monthly) basis and it makes sense. No, it will not allow you to conflict out trips. It looks like some of you guys are bidding an entire hard line based on what happens the first week of the month. Junior guys like PBS because with a line bid, a senior guy takes 4 weeks of trips based on maybe one or two trips he cares about. With PBS, a junior guy might get trips he wouldn't have received. Its about the language the company puts into the PBS. We can get 28 days (or more) off in a row for a 7 day vacation block. We can credit as high, or higher than line bidding. My two cents is that PBS works. If you have questions, I would seek out ExpressJet MEC guys that deal with PBS. You might be surprised. The company sets a credit window. Say.. 70 to 90 hours. You pick trips each week to add up to that window. Don't want to fly a lot and get paid 72 hr guarantee? This month our min is 60 hours. So I can bid three 20 hour 4 day trips, and get paid 75 hours (our min is 75). Or I can bid more trips and if my seniority holds it, get more than 90. Are you a commuter that wants the third week of the month off and like weekday 4-days? Tell PBS you want 4-days starting at 11:00am on Mon or Tues on the 1st, 2nd, and 4th week, and Flica will clearly show all the trips on those weeks, and you can even put them in order of preference, EACH week. You can submit 3 different bid sheets (if it cannot complete you on the first sheet, it moves on to the next.) Not trying to open up a ball of wax. I'm just commenting from experience with a company that reluctantly transitioned from hard lines to PBS. IF mgt is asking this of Spirit pilots, and it seems like it is pilots against mgt, seek out the the guys I mentioned and it could very well go in Spirit pilots favor. All bidding systems are based on seniority, hard lines or PBS. (Just do NOT select a "globalization" option).
