I don't think in this case there is a big difference between displacement based training events, and vacancy based training. If a bunch of 767 FO's and Capts bump to 737 Capt, which is the airplane that will be replacing their fleet, in their base, that training event is the same.

If a super junior 737 Captain gets bumped, what is he going to be able to bump too? More than likely a 737 FO, which he is probably still qualified to fly with just a PC in the right seat, or maybe just a few more days of training.

When bumps start higher on the food chain, like during a big furlough, the snowball starts at the top. The snowball gets very big, very fast.

In this case, maybe not so much. IMHO.

I am surprised the company is sitting on that many excess 767 pilots getting paid not to fly. Since they all live in Denver anyway, why not sit around getting paid for nada? I would.
