A pilot on Pinnacle's internal forum did this analysis. The fenced ratio is based on aircraft Captains divided by airplanes. The analysis is pretty accurate. Here it is, copy pasted:

Pinnacle needs to have a quota of 541 Captain slots on the CRJ-200. If the number is less than that, then the upgrade will go to a Pinnacle pilot before it goes to a XJ or 9L pilot. For the 900s, it's 95 Captain slots.

The point is that we have lost on this since our numbers are horrendously low, because these numbers are tied to our staffing model of Summer 2010 when the snapshot was taken. That is what Bloch used.

Summer of 2010, we had 126 CRJ-200s, and with 4.29 pilots per aircraft, the math was 541 CAs. Relatively speaking, with Mesaba's 19 CRJ-200s they bring in to the mix, their staffing was 5.26 captains per CRJ-200, so they get 100 slots protected.

Proportionately speaking, both XJ and 9L have much more fenced protections than we do simply because our staffing model was horrendous. Bloch even **bolded **Mesaba's staffing numbers on page 18 of the award.

The reason it hurts is because our staffing was so low in Summer 2010, and today, we have "fixed it" by a significant amount. That is to say, we have far more than 541 Captains on the CRJ-200. We have exceeded our ratios simply because management decided to increase our staffing. Had our staffing snapshot been taken NOW, we would have been much better off, because we would have protected more of our own CA slots for our own pilots.

When it comes time to upgrade, you say that we Pinnacle pilots have protected 541 slots. True, but we have protected those slots based on a staffing model of 4.29 captains per CRJ-200. Today, we stand far above that value, and have many more than 541 CRJ-200 Captains. Because our ratios are already met on both the 200s and 900s, we don't get any help by the fences. The next few upgrades will be XJ guys while they fill their ratios. And if Pinnacle guys leave, that's good, but the available slots will STILL be above 541. For us to gain any advantage, TONS of Pinnacle pilots would have to leave, to make our staffing model go from 5-6 captains per CRJ to 4.29 captains per CRJ. Then, the fenced protections would kick in, and we would get priority on the RJs while we filled to meet the quota of 541 Pinnacle RJ Captains.

But make no mistake, we have lost big time on the fenced protections, because the protections based on a staffing model that was in place at Summer 2010.

*************************************************

My comment: Before any XJ guys says (again) that you brought the staffing with a new contract: untrue. Our snapshot was taken July 2010 for these low staffing numbers. We had upgrades and newhire vacancies every month in July, Aug, Sept, Oct, Nov, Dec, Jan, Feb. The JNCBA was signed Feb 18. We had already increased our staffing to come in line with "industry average" __before__ the JCBA was signed!

I hope the merger committee disputes this fence protection, so it can raise the number of protected positions. The 60-day window is open, and time will tell.
