NJA just signed a new contract and has different work rules than NJI. The NJI pilots are currently waiting for a new pay schedule and work rules that will be handed to them by the management as they are non-union. NJA have over 2000 pilots and NJI has under 500.
As for basing, NJA has 5 bases that you can choose from and NJI still has home basing. But to get on with NJI you need the higher minimums, Gulfstream time and letter of Rec for NJI to be competitive for the interview. They get thousangs of resumes for a handful of jobs.
Here's the kicker - three years from last November there may be a merger of the two operations. And when I use the wrod MAY, I mean may. Don't count on it! But there will be a chance to fly the GIV & GV is you get on with NJA.
Hope this helps - and good luck!
BTW - If you meet other quals you might have a chance to fly at NJE, or Europe. They ae hiring close to 100 guys soon I hear.
