Looking at PSA Airlines | PSA Airline's Fleet Growth Schedule- Updated | February 26, 2015 and PSA Airlines | PSA Fleet Growth | October 22, 2015

So while the overall growth for PSA has increased by a total of 24 aircraft there has been a significant slowdown in the transfer of CRJ700s from Envoy to PSA.

In 2015 there will be 5 less transferred than originally scheduled
In 2016 there will be 11 less aircraft transferred than originally scheduled
In 2017 there will be 13 more transferred than originally scheduled

From November 2015 till August 2016 there will be no transfers of CRJ700 aircraft from Envoy to PSA, but they are scheduled to resume in Sept 2016.

Again this is based on PSA continuing to be able to Staff all of their flying. I've seen it mentioned on here a couple of times but what really counts for new hires isn't the number that are showing up for class, but how many are actually completing training. You could have a 100 new hires every day starting class but if only 1 is able to successfully complete training it is only 1 additional pilot.

It sounds like PSA's classes are 25-30 people every two weeks. But it also appears that the pass rate is around 80% (20-24).

Even though Envoy is losing the CRJ is the long term in the short term they will have to begin upgrades soon.
