Spaulding - thanks for proving my point. 80/yr = < 7/mo. Which is less than the 9 Mesaba can and will send during a flow. 9 is easily sustainable, given our training department and over staffed situation. The point is that the 20/mo was a shot in the dark by the nwa alpa negotiators and was completely unrealistic from the word go.
That may be a valid point regarding the sustainable number of flow-ups from Compass.
Each flow arrangement, CP and XJ, would have advantages under different circumstances. It would depend on the class size, and anticipated duration of the hiring.
Even the negotiators recognized that you can't simply lose and re-train 20 pilots per month at a relatively small airline, I'm sure that's why the CBA has capped the flow-up of only 25% of the total list.
If a flow-up does happen, Delta will have to take the first 20 pilots of each month from Compass. I'd envision that the top 20 guys each month would be given their numbers, and delayed as allowed in the contract to slowly meter them out of Compass. But again, they do get to establish senority.
If Delta were to plan on large class sizes every month for a year(hiring 400 people or the sort), it could be 80 from CP, and 108 from XJ for the year, with the remainder being "street hires".
If Delta were to hire less, say 160 pilots for a calendar year, it would depend on the class sizes per month. If the class sizes were 20 people per month, it would be 80 CP pilots occupying the first 4 classes, followed by 4 classes occupied by 36 XJ pilots mixed with 44 "street hires".
Different scenarios will yield different results.
