CommutAir is what you make of it. Great crews, good flying, well maintained aircraft.
Bases close and are downsized, happens at every airline. I am about to be displaced from my base, after moving my family here. And no, I am not happy about it - not in the least. I have been furloughed here as well. But I do not regret coming here, and do not regret any of the almost five years here. I have met a lot of very good people and had some good times.
When I interviewed here I was asked what my long-terrm plans were. I told them I would get some 121 experience, upgrade and get 1000-2000 hours PIC and hopefully in 4-5 years move on. They seemed agreeable to that plan, and I don't know many regional airlines that would be if you told them that in an interview.
Does CommutAir have issues? Sure. I bet if you asked the pilots at USAirways, United, Delta, Northwest, Comair and Air Wisconsin right now, they'd give you an earful about their issues as well. You don't have to be happy about what is happening, but if you think the issues will be solved by going to another airline, you are fooling yourself. Sooner or later the issues will crop up at your new airline.
So if you want to come to CommutAir, when we are hiring of course, I hope for the most part you will have the same positive experiences I have had - good 121 experience, fun flying and great crews.
As for larger major/national airlines wanting jet time, I can point you in the direction of 3 people at AirTran, 3 people at Continental, 1 at Southwest, 1 at UPS, 1 at Atlas, and 2 at Allegiant who have gone straight from a CommutAir Beech to those companies in the past year.
