There will likely be a "shortage" of regional pilots. There will be qualified pilots, but not ones that will take regional jobs. This will continue to increase as airplanes are shuffled around. There are guys that have been with an airline 15 years that are not willing to go to another regional when theirs goes out of business. The number in school now is simply too low to sustain the attrition.
This will have to lead to better pay/benefits, or the increase in amount of flying at the majors.
The other thing to consider at the Majors is the number of guys that were hired during the last "shortage". There were many young guys that have quite a bit of seniority and have been receiving good pay for years. Pilots working past 60 years of age will be the exception, not the rule. If people can retire at 62, they will.
