From the latest Jetstream:

"2) As a result of the new ATP requirement for pilots in part 121 operations, what will be the impact on pilot supply for part 121 operations? For part 135 operations? For part 141 pilot schools? For Part 142 training centers?

The new ATP requirements will adversely impact the staffing needs of all air carrier operations. Since October 2010, ExpressJet has hired approximately 790 pilots. The rules currently proposed would have eliminated almost 400 pilots that ExpressJet hired. That equates to the staffing of approximately 40 aircraft that could have potentially been parked on the ramp due to lack of staffing. With the Aug. 1, 2013 First Officer ATP requirement rapidly approaching, ExpressJet has been adjusting hiring requirements to meet the requirements of the law. In March 2012, the airline ran out of applicants who had the qualifications that meet public law 111-216. This has occurred 17 months prior to the enactment date. It is obvious that a pilot supply shortage has already occurred and will only deepen as retirements and other regulatory enactments occur. It should also be considered that pilots, who are already burdened with high debt loads exiting training, will now have to come up with additional funding to bridge the gap in flight time to be qualified for air carrier employment."

Of course, the company could be completely lying...this was their response to the HR5900 NPRM. Tighten the supply of cheap labor and of course the company would say something like this...Food for thought though...
