No school can guarantee you anything.
The worst thing you can do for yourself is choose a school based upon what you think they're going to promise you and then meander aimlessly with an entitlement complex when no one's calling you.
In the airline business, largely no one cares where you've trained. We don't sit around the simulator break room talking about flight training institutions, we're talking about previous
experience.
Choose a flight training environment (FBO, Academy, some-dude-with-a-cessna) based upon your learning style and amount of organization you're willing to pay for/deal with -- NOT for what anyone is promising you.
I went to Riddle, I spent five years being told that I attended the Harvard of the skies, that I was the best of the best of the best and that (at the time) United was going to be beating down my dorm room at any time begging me to join their airline.
Not so.
Here's the key to a successful civilian aviation career start:
a. Pick a flight school that best matches the training environment you're looking for. If you'd like to be casual and be spoonfed material, I wouldn't suggest an accelerated program. If you're not a self-starter, you might want to choose a more casual environment.
b. This sounds brash and may to upset you, but learn to ask more questions, keep your opinion to yourself and listen to guidance, even though it may be 180 degrees from what your preconceived notions are. Do you see me preaching to Staplegun about flying the ER? No? Why the heck are you preaching to Zmiller about regional flying?
c. Network. The same regional/narrowbody FO you're saying is full of bunk in this thread has a 99% chance of being the guy you're going to be begging for a letter of recommendation from or sitting right across the interview table from.
Turn down the rhetoric, open you mind. Be open to seasoned opinions that may not match with how you think professional aviation works.
