FTB,
Good spread sheet.
So you worst case assumes that the 1.25 mainline jet to new 76 seat jet acquisition language in 1 46 f is entirely used for fleet replacement to draw down existing aircraft, while also drawing down to 125 50 seaters ... could happen I guess. Your assumptions imply you hate the MD88 more than I do.
What does the model look like if the 717's and 739's are used to trigger the 3 to 1 language?Good analysis.

Here's what I mean, short story, just look at Net Additional Airplanes, Lost Jobs and Pay Difference. Option B is 717s as pure growth and Option C says not so fast, 717s/CRJ-900s replace MD88s.

I hid a bunch of the other options for clarity. FWIW, the 739s are in there as a 1:1 replacement with the 100 oldest 320s, 763s and 757s and so it takes into account the hits with ASMs there and parking the CRJ-200s.

You option (B) is the one one that the ratios are based on as I understand it. 1.59-1 is the top end and we are planned (slowplay's number) to be at 1.76-1. That adds a min of 600-700 jobs with a top end of 1100. As I said in the other thread, those jobs are the initial accumulator until section 1 language is triggered and DCI is even forced to park 50's or 76 seat jets(their choice)
All "known" fleet replacement plans are part of the ratios, but as I understand it, the 717 IS NOT. The ratios get to the top end compliance with DCI 50's being parked.
George and you have proven how the same block hr plan will get us to 1.59-1 with no mainline block hr growth. The compliance will come quicker due to the tables and contract checkpoints that force 717's to be delivered to get more 76 seat jets,but the end result is not 1.59-1, but 1.76 to one when everything is considered; 717, 50's parked, 76 seat aircraft added, 767's,757's,m88's,dc9's, and 320 retirements.
My math showed a mainline fleet count of about 770 or as you show 647 domestic jets. The math works and gets us to about where we were at SOC, abet on lower paying jets. Again the planned ratio puts us well above 1.59-1(1.76-1) meaning that if the economy goes south not of the triggers to pulldown DCI, nor the non compliance language(my concern) apply, until mainline domestic shrinks by 17 basis points from 1.76-1 to 1.59-1. The new hires brought in below us are the first accumulator. Then depending on what the trigger was(euro zone debt crisis which caused the economy; apply w/ the non compliance language?) DCI can or cannot be shrunk in relation to our capacity restriction.

Ironically, Delta could adjust all the capacity it wanted if they'd just fly 100% of their branded operations in house. Too much to ask, i know. Outsourcing is okay.

To keep things fair, I need a -1% ASM YOY growth. I can do that, but I can also do that cutting out 120 CRJ-200s since we know those are uneconomical. That'd give you DCI 479/255 instead of 450/325. It's all about the ASSumption and given the TA doesn't require growth, you can go a lot of ways. I tend to believe DCI 450/325 will not be shrunken though so to get a 1% or 2% decline in YOY ASMs I had to take something out, the 88. I guess I could take out 319s too?
Anyways, I'll post it for you in a bit but 3:1 ratio is a 14 aircraft mainline gain and 150ish pilots, and I kept 50 MD88s of the 117... for old times sake. Gave me a -1% YOY ASM change.

I loved the DPA guy who was upset they did away with trip parking.

Did it ever occur to you that Delta really wanted more 76 seat RJ's all along? The 80/82 seat could of all been smoke and mirrors to achieve their desired goal of more 76 seat RJ's? This leaves the Delta pilots feeling that the additional outsourcing of more 76 seat RJ's was actually a win.
nwa, I hope you're right and we don't give up more in three years. So far every contract going back a decade has given up more and more scope. If during record profits coming on the heals of our massive sacrifices we are giving up more scope I worry about the next downturn. The trend line is still giving up more and more large RJ's. But I suppose we'll get em' next time! Wait a minute, this is next time!
Any yet again, management moves the ball closer to their goal. Outsourcing as much of the domestic fleet as they can.

I'm sure you made a great grade in Excel 101, but you probably need to retake statistical analysis.

You are changing numbers to fit your theory. Your option c shows a reduction of over 400000 block hours in the delta domestic system. That is nearly a 20% reduction from current levels. I will concede that there will likely be a decrease in total block hours that accompanies an up gauging process like this, but I doubt it will be of that magnitude. Even with this ridiculously biased assumption, however, you show mainline jobs as stagnant under the TA. Now consider what the mainline jobs picture would look like if delta had a 20% reduction in domestic block hours WITHOUT the protections included in the current TA. I don't think even the most optimistic of us would believe it would lead to no reduction in mainline jobs. The company can add or subtract total block hours with or without this TA, the difference is that with theTA we are guaranteed a larger share of whatever flying Delta does.

But as the numbers show, best case pro TA scenario of pure 717 growth + 7 MD90s - 17 DC-9s and you've got a total fleet with DCI 450/325 that is 6% smaller than it is today.
Best case pro TA scenario, we shrink in total by 133,000+ block hours or 4%. They're telling us that they will drop ASMs.
Now take that significant 4% drop and say the company decides to park MD88s via the 717/CR9 tag team. Because at some point, there will be no MD88s in this fleet. And in doing so they eat maybe another 0.6% more YOY drop in ASMs over the best case pro TA scenario 4% drop.That's where you get a 400,000 block hour drop or a 1.89% drop per year. We're already doing 1% drop last year, why not a little more in the name of refleeting?
And that drop is even less YOY when you consider the time it will take for the 739s to all be here. If you didn't notice a 1% drop from 2010 to 2011 I doubt you'd notice that one, except that there would 325 outsourced jumbo RJs helping out the cause.
And fwiw, I gave the best case and tried to develop the worst case and let people see the estimated difference. No harm in that right? You can focus on the growth only side if you want, I don't trust it. And that drop is even less YOY when you consider the time it will take for the 739s to all be here. If you didn't notice a 1% drop from 2010 to 2011 I doubt you'd notice that one, except that there would 325 outsourced jumbo RJs helping out the cause.
Now given what we've seen since 2008 when we had a 767 mainline fleet drop to 720, a domestic fleet drop by 6%, and a reduction in pilots on the seniority list, etc, do you think they'd grow or shrink?
Pure mainline growth and a cost increase?
or
Some sort of capacity neutral refleet that saves money on pilot costs?

It's not a 20% reduction. A 20% reduction would be 2.8M block hours. I put it at a 13% reduction in block hours but ASMs only drop 6%.
