I am currently an E175 typed pilot with 700+ Part 121 hours and 2400tt (no degree), so obviously a little on the low side for NK and F9. I am looking at ExpressJet as hours and upgrade opportunities dry up at my current carrier. Few questions...

I am assuming IAH an obtainable out of training, if you go to the 145 and will last for the foreseeable future?

Still looking like upgrade will be available once the 1000 Part 121 hours is reached?

How long is reserve on the CA side IAH E145?

What is schedule flexibility like?
