I highly recommend RAH. I'm not sure what pages you read in the RAH thread but I don't think anyone suggests expressjet over republic. They are a great pilot group who is having some really unfortunate stuff done to them by their parent company. Also, the overall consensus here online and from those who I talk to is that we at RAH are in a good position. Healthy staffing but a growing fleet, ownership by all 3 majors, and a pretty decent current contract. We're also not stuck with any out of favor aircraft. Upgrade will be under 3 years by the summer. I am on pace for upgrade just under 3 years now.
Things at republic are very different now than they were 2 years ago.
