FYI: ALPA addresses pilot availability:
ALPA: Airline Pilots In Strong Supply For Right Career Opportunity | Aero-News Network
ALPA is wrong. There is NOT a strong supply of pilots. For example, a pilot for either UPS or FedEx recently posted of info from a meeting with their Chief Pilot. They were told within about two years, their applicant pool will have shrunk so far, they will not be able to recruit enough pilots for their operation.
