It is getting faster for the newer people and it will get much better once they have caught up all the orientation/indoc classes of 60/45 people. They have made the classes smaller on purpose, to decrease wait times and get us flying asap (which is what we all want!).

My experience so far:
Feb 16th orientation (#6 from top of seniority OF THAT CLASS)
March 7th indoc ( #3 from the bottom of 15 of that INDOC CLASS)
people ahead of me have already been called back to the next part of training and MY specific Finish date is JUNE.
Which is still within that 3-4 months training timeframe that all the other regionals (that i have talked to friends at) listed below.

I tell you this to give you insight (& hopefully less not more worry) because we are all so type A we hate feeling blind to our future XD. But i wouldnt stress about it taking along time, it is across the industry, and we are getting paid nicely, 65hr monthly guaruntee starting from orientation date plus perdiem the whole time until IOE complete. We should just use this awesome extra time to study more and not feel so crammed with studying so much so fast. and travel! Use Flight Deck Jumpseat privileges! its AWESOME!

Mesa: finished ATP/CTP waiting for sims 6 months on E175, less wait on CRJ200
Skywest: 3-4 month training (from Indoc start) including 4 week delay from ATP check to IOE trip, only got .8 sitting reserve for the first WHOLE MONTH after IOE completed
Republic: 3-4 month training (from Indoc start)

like others have said, we are loosing sim and check instructors/captains (ones who can do IOE trips) and amount of sims avail are all causing bottle necks, BUT no forced upgrades yet is good.

ALSO Envoy itself is on track to RECEIVE 3 MORE E175 SIMS by the end of this year so that will also ramp things up. Not to mention the fact that at envoy they have a training program called Advanced Qualification Program, which means they basically wrote 8 ATP checkride scenarios and the DPE choses one and thats what we fly, so we will know exactly what to expect for our ATP check.

So far management/training are nice and they just are covering their bases by having a large backfill of pilots ready to start training at any time. they usually give you a few days notice for the next part of training but you can request up to 7, youll get pushed back though to the next class. People cant come for several reasons, sick, covid, etc and thats fine with them but they like having the large amounts waiting incase for those reasons. Of course COVID is dying down and that was throwing like a quarter of the classes out at a time for mandatory 2 week quarantine. So maybe thats another reason why classes are smaller.
