For the top half of the list Colgan pilots would strange mixture of 2:1 3:1 all the way up to 6:1. The bottom half of the list would start at a 2:1 and then work down to a 6:1 in some cases, then back down to a 3:1. Excel is fun. Of course I may be doing that wrong, I assume if I say 2:1 that would mean 2 years for every one, or 6 years for every one.
Mesaba brought the highest paying aircraft and a contract that we are all on now, except for some concessions to Pinnacle and Colgan for their own desires that they wanted on the list. Since Mesaba pilots on the top half of the list have received nothing of substance so far except for the one contract one list. Quite frankly it's irrelevant to many of us, since our scope would have simply pushed our existing contract rates onto Colgan anyhow, nuy I think Pinnacle would have whipsawed Pinnacle and Mesaba.
I hope I'm not rambling, these all seem like relevant points, I suppose the real question is, did I answer your question?
I can see where you're coming from. However, from past seniority award arbitrations that I've read (CHQ and S5, DL/NWA, and of course ours) as well as I have been exposed to (AA/TWA and AmWest/US and Piedmont, PSA and Allegheny) Relative Seniority is a concept that plays out, unless one group tries to protect a certain segment of pilots (Airways with the widebody flying).
Where you lose me is how you're having DOH play into relative seniority.
Here's where I'll hedge my bets:
At the top of the list, you'll see a ratio highly favorable of XJ guys vice PNCL. Perhaps even just DOH until the first class of PNCL. Then the next group will be a mix of CAs. This group will probably reflect the various hiring spurts at various airlines, and this will probably be repeated with a fresh start several times, each of which will be a slightly different ratio.
I think the obvious thing is the DOH issue, as we get into the 2000's where some carriers hired and some furloughed and some stagnated. You'll see disparate DOHs, so for example, after his last hiring spurt from, oh, 2007 to Date of Constructive Notice, is where you'll see the most "chaos". For example, and I'm completely making this up, you'll see a 90% PNCL FO with a DOH of 07, a 70% CJC FO with a DOH of 08 and a 95% XJ FO with a DOH of 05. Don't be surprised if the CJC FO is senior followed by PNCL and the XJ guy is last of the three. Then there are spots where the 95% XJ guy is now bidding 80%, the PNCL guy is bidding 90% and the CJC guy is 95%.
The higher up in the list, the more of a chance you'll see a fence or a no-bump/no-flush deal to keep a wholesale hosing. (Which, to answer another question not asked, will prevent the "windfall" when the master list makes folks cry in their beers)
At the end of the day, CherokeeCruiser won't be senior to all the Colgan CAs. Or even the Colgan FOs. Sorry about your luck.
