While interesting data, I would say that the fleet numbers are probably incorrect for many of the airlines you have listed.
As a UCAL Holdings Pilot, I have no doubt (and we have been told through numerous ACP's) that the UAL 757's will be parked first, as we receive replacement 73's. On top of that, I wonder if you figured in the loss of the 767-2 on the Continental Side. That fleet will be gone by early part of next year (just got an email from a CP about that) (plus the last few 737-5's). The replacements are suppose to be the 787.. but they will not be here before the last 76-2 leaves.
I do believe that UCAL, along with many of the other carriers you have listed.. will be hiring in the future. Just not in the numbers you have mentioned.
Will be interesting to go back to this thread in the next few years and compare.
