Closer, and a little low this time.
Nope - but you probably don't realize that US has pilots retiring from furlough. So that 1987 hire or 16+ year furloughee will get no benefit from more junior pilots retiring.
Then there's the non-active above them on the list. If a pilot who isn't working (disability, etc) retires, what advancement does it result in for the pilots below him on the list? The non-working don't vacate a job when they retire.
You see, US also has a pretty high percentage of non-active pilots who will leave no vacancy behind when they retire. So, nobody will see movement equal to the total amount of attrition. Even the most junior furloughee will only see his actual number change that much, but there won't be recalls above him equal to that change solely due to attrition.
Nope - the last East pilot on the list is #4691 if you extract the West pilots from the award. With under 2500 retirements in the next 10 years, that would make the last pilot #2200+ - a junior Group II Captain. [Edit - I shouldn't say that since the last bid result I have is Jan or Feb. So you tell me, Bud - which "widebody" job will a 2200 seniority number hold?]
As you can see, if the pre-merger expectation was that the most junior East pilot would be a widebody Captain in 10 years because of attrition, the expectation was wrong.
Of course, if you think the arbitrator should have granted everyone's wildest dreams instead of realistic expectations, that's a different story.....
Unfortunately, I don't have a West seniority with DOB and DOH so let's assume for a moment that USA320Pilot was right about West attrition averaging 50/year for the next 10 years - 500 total.
On the arbitrator's list, the junior (East) pilot is #6520. That pilot will benefit from both East and West attrition, or a little under 3000 retirements. So in 10 years (if he hasn't retired) the most junior (East) pilot will be #3500+/-. I can hear it now - see, I told you I was robbed!!!
However, assuming no changes other than attrition, the combined fleet is about 65% bigger than just the East fleet. Which means about 65% more Captains. That means that the current junior East pilot will be - amazing isn't it - a junior Group II captain. [Edit again - You tell me, Bud - with a combined fleet of almost 360 airplanes instead of only the 220 plane East fleet, what will a 3500 seniority number hold?]
Now what's all this about expectations not being being met.....

[Edit #3]
I finally got out the calculator. The combined fleet is 64% bigger than the East fleet. If that means even 60% more captains, that junior (East) pilot is ever so slightly better off than he would have been staying separate - there are only 59% more people in front of him.
The bottom active pilot with 20 years just went junior to a 1998 higher. Hard to imagine a number of 4000+ for that guy when USAir has a fleet of 220 or so.
Chances are the bulk of your 99 and 00 hires would benefit from attrition.
