As for the CRJ issue, the list will simply slide down, pretty obvious what would happen. The CRJ's crews are mostly senior, so either they will displace over to FO on something else or will upgrade, something they may have been stalling on knowing this was coming.

As for the bumping people out of a base, well that's just the way things work in a seniority system, just like bumping someone down the list when you bid over into a new aircraft and are senior. Yeah it sucks for the person, but they will be able to bid back and one day it will be their turn to have that protection and seniority.

With all the forced upgrades, we will continue to see people moved up and down lists and potentially in/out of bases. Once the dust settles it should be more predictable. Lastly, a DEC should have known what they were getting themselves into by taking that deal. It has been warned all over this forum and they are not new to the industry, so you get what you got paid for.
