I remember a few years back when I began researching flight schools and Universities. I won't ramble on about my experiences, but one thing I learned is to DO YOUR RESEARCH! Visit the schools and speak with current and former students. Ask about them on forums too. I remember I almost got suckered into doing my PPL at a local school. The CFI lied his head off to me, and put me down once I told him my final decision to train during University. Do not get a biased opinion, but ask as many people as you can. I am very pleased with the school I am at now (apart from the wx and a/c cancellations), and my instructor is the greatest! I'm glad I chose the route I did, and wouldn't go back to that other school if he offered me free training. The guy didn't care about me at all, but just my money.
Also, I remember how I had come across so many of these F/O programs and accelerated programs. There are no programs like this in Canada, nor are there any academy type schools. There are college programs (no degree though), and only one University degree aviation program school, which I attend. When I saw all these adds by schools that promised right seat turbine blah blah blah, and I got so jealous. I thought that was the way one needed to go. Their adds are so deceptive, and I feel easily mislead young students. I mean, showing a guy in a 747 or similar while advertising to do a PPL is ridiculous to me.
Anyway, keep asking around. Some of the schools like ATP, Comair, and FSI apparently have great reputations. Not everyone is happy going there, however. Do what makes you feel comfortable. If money is a problem, go part 61. If not, I would prefer (this is just my opinion) a part 141- I like structure. It's all about attitude in the end though. Stay positive and persistent and your career will be a blast, no matter what you're doing.
Good Luck in your search.
