No roasting on my end mate. Sorry if I came off like that.
Trust me when I say this, in aviation don’t believe everything to hear. Unless it’s on paper (even this is debatable lol) . Many aviation schools have pipeline programs with multiple regional airlines. And some have a flow through to the majors like you have mentioned.
As an example look at atp ( I am not promoting them, just using them as an example). Atp program runs 130 days ( I think) with all your certificates. You will also have interviews lined up with them as they also like your school have agreements with multiple regional airlines. The differ is tdifference is that you will get done sooner with your certs and be off to the regional in roughly 2 yrs working as a cfi while you would still be a sophomore or Jr in college working on your commercial license and will take roughly an additional year build time as a cfi to get reduced hiring minimums (since you went into a 141 school) the difference is 3 years. That’s 3 years of pay, and seniority you will be behind in.
Again, all I ask is do your research. :) all the best
