That's like saying had it not been for the large number of early outs at Delta you would not hold the seat that you hold.
It is what it is regardless of how it came to be.
You're right that it is what it is and just like during the contraction post 9-11 the category lists will start to resemble a stove pipe.
As for the seat I hold now, I'd have held it with or with out the early outs that ended nearly 4 years ago. Of the 3000 retirements between 2001-2005 all but about 300 were either on LTD, not in the top of the list or would have retired at at age 60 prior to 12-2007.
