I expect a fence around the crj700/900. As far as the crj200 and emb145, who knows? Same size and will end up being the same pay, so other than training cost to switch aircraft, I see no reason for a fence (company may not like the additional training cost).

I wouldn't get too upset about it. From what i hear, you will probably have anywhere from 2 to 4 years seniority (at least!!) before the lists are intergrated.
