All kidding a side the upgrade deal is pretty straight forward. 4 conditions must be obtained. 1. Seniority 2. Experience 3. Performance 4. An open spot. Any one condition is a deal breaker. They will upgrade out of order if performance or experience aren't there but they work down the list then go to the street. We are flying a large, complex, fast, transport category turboprop on demand, at night, all weather, into dark holes in Mexico and random airports any and everywhere else you never knew existed on a whim with long flight / duty days. They demand solid performers in the left seat and will not compromise (rightfully so). If you do a good job in the right seat and the other conditions are met you will upgrade and as of today its < 1 year. YMMV
