I don't think legacy carriers will have a shortage. And an extra two years really won't do anything. Only a small percentage of guys would work past 65 anyway. Regionals will have to continue to add pay and benefits to attract pilots in the next 5 yrs.

1500 hour rule is viewed as a safety thing and was made after Colgan so good luck getting that reversed. 1500 rule has helped to increase pay, it's a good thing.
