Comair Academy
I interviewed for an instructing job there in 1991. I was not impressed at all with the place. I did not care at all for how I was treated at my interview. I didn't get the job, which is one thing, but what bothered me more was that I didn't even get a rejection letter. I paid my way from two-thousand miles away to attend the interview. I also thought the aircraft were ratty.
Now that I've gotten that out of the way, I know that the program works. I also know that not everyone who starts at Comair finishes there, and not all of those who finish get CFI jobs. And, not all of those who get the CFI jobs get "the interview."
I have no idea whatsoever if you can continue to work there if you don't get "the interview" and/or if Comair doesn't hire you. Of course, the CFI you earn there is good anywhere.
The best thing that you can do is visit the place and see for yourself. Also, ignore the "career counselors." They are nothing but salespeople who are trying to get you to sign on the dotted line. As always, the bottom-line of a flight school is if it furthered your objective. Accordingly, see if you can find a Comair pilot(s) who went through the program and ask them what they think.
I promise that I have absolutely no agenda because I am not in aviation right now. Having said that, let me suggest that while you're in Florida that you take a 1½-hour drive to Vero and visit
FlightSafety Academy. I worked there for just over a year, and while there was plenty that I didn't like about the place as an employee I can vouch for the program as being quality training. Some of the quality people who were there during my time are still there. No direct "bridge" to an airline of which I'm aware right now, but plenty of FSI grads get regional jobs.
Maybe, while you're at it, you can drive down to Fort Pierce and look at
Pan Am International Flight Academy. I don't know the place personally and have heard pro and con, but looking at it and FlightSafety would be worth your while in terms of comparison shopping.
Hope these ideas help. Good luck with your choice.
