The article says they are looking at reducing the TT requirement for military pilots to get their ATP from 750 hours to 500. While the military used to be the prime source of airline pilots I don't believe that is the case anymore. And given the years of commitment once military pilot training is completed and the tempo of US military operations I don't think many pilots are getting out with under 750 hours.
The article is also wrong when it says as recently as 2013 pilots needed 1500 hours to be an airline pilot. In 2013 pilots had to have 1500 hours to get an ATP but you only needed (per the regs) a commercial certificate to sit right seat in an airliner.
