Here's my story...
I ended up turning down the job offer after thinking long and hard about it. (I had 2.5 months) If they had contacted me a week after the interview, with the excitement still fresh, I would have gone, but I had a lot of time to think and...
Basically, 5th yr 190CA makes the same hourly rate I'd be making as a 14 yr CA at my regional. (from Airlinepilotcentral.com. Yeah, I know, time and a half...) And that's without the years as an FO making less. There's no real profit until A320CA, and Dean M. the fleet manager said *in my interview* that that could be 10 years. Top that with commuting to JFK from a non - JB city, and the choice eventually made itself.
It's really too bad. I love JB and think I would be very happy there. What I don't love is NYC, (in fact, I despise the place) or the thought of commuting for the rest of my career. I heard "just wait 2 years and move to FLL," but remember, when you upgrade it's back to NYC for a much longer period.
This is not intended as flame bait, or to talk anyone out of JB. As I said, I truly admire the company, but for me it came down to the slow "return on investment." And the commuting thing. I'm lucky enough now that I don't commute and never have. As I get older I feel that it's something I just don't wish to deal with for more than my first year with a new company.
Good luck with your decision...
