I am currently an F/O for ACC. To the day I have 450TT and 50MEturbine. Upgrade time is only restricted by the total time you have. If you come to the company with 1200TT you will be typed in the Shorts and fly the line for a month as an F/O before flying as captain. Some people in my class went into training with the flight time and got to the sim and turned down the type rating and went for F/O. The company is very short on Captains. If you have the time and you stick with it, you will most likely be a captain. The company has on-demand cargo charter and scheduled runs for DHL and UPS. I can only speak for the scheduled runs, you will log block time of around 60-90 hours per month. There are some bases in Oregon and California that will log less than 50 per month. Send me a message with any other questions.
