Uh.. It's exactly like Gulfstream. As your 2nd paragraph says, you are paying to take the training course. Why would anyone pay 25K to take a training course? It's border line idiotic because you'll pay for free training and also you won't get any respect from your fellow pilots. And please don't compare ATP's CRJ course with Jetu. ATP's is totally different than JetUs.
No, research the Hot Archives thread some more.
Gulfstream Academy is an entirely different animal because there, you pay $30k so you can SIT RIGHT SEAT for at least 250 hours for Gulfstream Airlines. At Gulfstream, your $30k guarantees your a F/O position at Gulfstream Airlines and as a result, Gulfstream Airlines NEVER hires First Officers off the street.
Now that above is true hurting the industry.
Jet U is not a buy a job program. All you get out of it is an interview.
You could blow it and end up on the street.
The bottom line is at Jet U, you don't pay $27k and then sit in the right seat of a Pinnacle Jet (that's the analogy equivalent of what Gulfstream Academy does with the B1900 at Gulfstream Airlines).
See the difference?
As far as the ATP CRJ course, you're right, it's not the same. It doesn't compare anywhere near Jet U's.
ATP is a 7 day (1 week) CRJ crash course. Jet U is a 13 week (that's 3 months) of nothing but CRJ systems, procedures, FTD training, simulator training, profiles, etc. It's much more thorough than ATPs CRJ course, it's longer, more indepth, and it covers the entire initial Pinnacle pilot training in those three months. So, Jet U has a bigger program, and hence more expensive (almost 4 times as much).
