The numbers that Rick Wilson published about a month ago support the update/flow times that the company is advertising. 20 CA Flow, 8 CA leave for other jobs, 8 FO leave. All were an average. Those numbers add up to exactly 2.5 yr upgrade/6 yr flow. I'm 7.5 in, still an FO don't expect to see a bid this year that would include me. I don't drink the coolaid just putting the numbers up for those pondering how/where is all coming from. I believe that there is more to life than chasing one of the big 3. Personally, Alaska, JB, VX, or Spirit would be better options because they treat their employees well, have an attainable growth plan and more potential than the big 3.
