I heard the same thing from my furloughed friend. 600 new hires in the next year. However, that doesn't include any growth, only retirements (if I understood correctly). Retirements ramp up quickly within two years to rather large rates. However, the flight schools have known this for years.
I also received an email from the company, instructing me to update my profile. Got about 4300 hours, lots of turbine, no jet time. Keeping fingers crossed for the time being.
