USA Jet is a good place to WORK... I was there a couple years and had a good time. They're a really good bunch of pilots. Well qualified and hard working. Looking back they provided me alot of experience and still paid a wage that was fair. Pay was above the standard commuter wage. You will hear groans and moans from folks, as anywhere. If you work with 'them' it can be a great experience. I dont like the contract thing, but you have to be there a couple of years to get your time anyway. I would say sign it and forget it..
Sometimes it is tough sitting around waiting to fly. It can be very frustrating to be called out at midnight and flying all over the country with long duty periods. All in all, a very safe place to work and a good bunch of folks. Dont apply thinking its a 'cushy' job. Its work, but a good environment to learn and grow.
