1.) Which airline(s) would have the fastest upgrades(approximate times would be greatly appreciated)?
5-7 years depending on base and equipment
2.) Which airlines would allow for new hires to be based at domiciles on the East Coast(e.g. MA, MD, NY, NNJ, PA, FL, VA etc) either due to lack of competition for those bases or a general tendency for new hires to be placed there.
JFK and CVG are available to new hires
3.) Which of those airlines are performing poorly and are likely to go under?
I have no clue...
4.) Which major airlines give preferential hiring for those airlines?
I really dont think it necessarily matters, as long as you have your 1,000-1,500 TPIC, you've got a fair shot.
5.) What is a typical avg schedule for a new hire F/O for each airline?(e.g. 4ON, 2OFF etc)
Up to 4 day trips, I have heard some people have flown longer in the past, but usually a couple of days off in between trips. Reserve is a different topic though.
6.) What is a typical avg schedule for a recent upgrade junior capt for each airline?(e.g 4ON, 2OFF etc)
Not sure
7.) Which of those airlines have a sound reputation for(relatively speaking

) treating their pilots reasonably well and having trade unions?
Comair has a great training program and puts you up in apartments or hotels for training. We are ALPA, it is both good and bad in different ways, but I'm sure glad we have their representation.
8.) How many of you guys have been trained and/or instructed at Ari-Ben Aviator Inc?.....if any...plz PM...I would like to hear your experiences.
I built 50 hours of ME time there a while back, was a busy place, seemed like solid training though. Hope this helps.
