I worked for Skyway for 6.5 years and I enjoyed everything about it. There where times when I hated the job, but that was my own fault and not the airlines. I commute to California, and to add insult to injury I now commute to JFK.
The training at Skyway is second to none, and if your not a good pilot when your done there then nothing is going to help you. I flew the 1900 then the 328 as both Captain and as an FO. Everything that I learned I took with me to my current 121 gig, and it worked because I made it through training without any trouble.
It's a small pilot group and you get to fly with everyone, and get to know everyone very quickly. They are more like a family than any other place that I have ever worked for.
So if your asking yourself if you should go, there are things to consider. One the 1900 has no autopilot, not really a big deal but if you want your skills to improve then go. The upgrade time is slow, but if your goal is to build good time and move on to a major your going to have to fly. right or left seat. Last time I looked the min's where I now work are right around 6,000 hours.
Your going to fly into small airports, and some large ones. Both are going to expose you to every aspect of aviation. The men and women that you will be flying with are great. People know your name and your not just a number there.
The down side is as with all regional airlines is the pay, the days are long and the winters suck. Then there is Milwaukee, if your from there great if not then your going to be bored. But you'll have friends and there is plenty to do in the summer time.
So low time guys and gals go for it, even if your there for a few months. The training is worth it, and it gets you into 121 flying. That alone is worth it's weight in Gold.
Good luck!
