1- No help with finding housing, however, a quick search on something like apartments.com will get a boatload of info. I never really had the stress of moving that was suggested earlier, i always found it fun to move around alot, and yes my wife and daughter liked it just as well.
2- Guaranteed a/c is another NO. You will be trained in the 58, but as has already been said as well, you may fly anything that the run you select has on it. You will also not know your run until you pass that 58 ride, so asking about junior bases is completely out of the question until you get your first ride and then talk with Quinn about open runs.
3- I believe the answer to your last question has also been answered.
So are you looking to build the infamous multi time to move on after a year? Just wondering, because i have seen this happening a lot lately. Airnet has become a multi time building airline so that people can move on after there year is up and go fly an RJ. It used to be a good place to stay for a career, if you didn't mind the nights. Now with pay cuts and no more raises, it is been downgraded to timebuilding only pretty much. I have yet to hear of anyone hired in the last year or two who wish to stay for a long time. Most of them don't even stay for the jet anymore, they know they will make more money and have about the same upgrade time going to a regional.
NYCpilot...yes, we will hire SIC's, i think the average is around 1000tt. Back in the day they hired MUCH lower time guys, and i bet we will see this happen again since we are hard up to find pilots anymore. I was hired with 500 tt and a friend of mine was hired with 425tt...most of it was multi, but back then they would hire very low time guys and put them into the system to build their time. Both of us got 58 runs out of DAL and TUL...not high time runs, but back then they would let you choose the run you wanted to SIC on. It took 8 months to get the 135 mins, but it was nice to get used to flying the way we do and learn what was expected of us before we were thrown into a 58 right after passing your checkride. Ahhhh....the good ole days of Airnet, man what happened!
