My dos centavos, for what it's worth. Ground school to sims took 3 months for me. Sim training was big hit or miss because the instructors were pretty good overall but the system itself was not up to par, in my experience. There's a lot of study and figuring it out on your own throughout training, not a lot of teaching. So if you don't have much high-performance or ATC airspace experience you might, again, MIGHT be behind the curve, at least that's what I saw for me as I had such experience that helped me. We were finding stuff out at the last minute either from just randomly reading the books or hearing from other students' mistakes that no one had taught us basically almost until check ride day. That being said, I did hear a few months ago that training was getting overhauled, for better or for worse, I don't know but it sounded like the instructors were going liking the changes that were coming to the syllabus. As far as the check rides (KV and LOE, not including the MV because it is mostly a cadence) it definitely sounded like the experience was heavily depening on the instructor and how they felt that day but i did hear bad stories about some LOE instructors that were failing people intentionally to include for being military, like someone else just stated here--not sure how accurate that was/is but I definitely heard some of them having that reputation in the past. I believe that as long as you have a good attitude, be honest when you don't know something, and show what you know you will be fine.
I'm hearing from folks that finished their LOE that they waited an average of about 8-10 weeks before being called to go fly IOE. Like someone else said, you will be paid at the 75 hrs guaranteed and you will have call-in days, twice a week, to check if you are assigned or not every week. Yes, it sucks as far as not being able to fly that entire time and rack your hours, but it work for others that may have another flying job.
Take it or leave it, at the end of the day it is still a regional and IMHO a regional is like an ILS...need i say it? Find what works best for you, i have not heard good things about PDT, Mesa, or Skywest mainly regarding QoL but it sounds like you will finish training faster than PSA. Again, find what works for you, at least temporarily (idk of any folks that get into the Regionals to make it last a lifetime) My two cents....
