There are very few FO's at Mesa right now that can upgrade right now, at this moment in time. Everyone is busting their butts for open time to get their 1000 121 time.
What you can expect is DFW as a base, very short time on reserve as an FO, and with your 121 time, most likely the most jr guy to upgrade thus far. You can also expect outrageous medical benefit costs if you need it for a family. PSA is hands down the winner when it comes to medical benefits.
