I just spoke with a recruiter who told me Mesa upgrades at 1,000 SIC of 121 for the E-Jet out of IAH. I was also told IAH has about 2 months of reserve, and the average upgrade time is 21 months for IAH/E-jet folks.

Can anyone attest to why it would be 21 months? Recruiter said CRJ upgrade is taking about 14 months, which seems much more plausible.
