Competitive Mins? I don't think anyone can answer that question now. I was hired in the last class, which was back in February. I can tell you I had 3,100 hours at the time with 1,200 turbine PIC all in turboprops. The state of the industry has changed and there are more to choose from and they can be as picky as they want now.
How long on reserve to the month?! Hahaha! Again, see above. I've been here since Feb. and I'm still on reserve, along with everyone in my class. However, before us, people were only on reserve for a month or two at the most. If hired in Oct, expect to be on reserve for a long time.
How long to upgrade? Well, the most junior captain upgraded in Jan. and spent about a year and a couple of months as an FO. I expect it to be AT LEAST 2 years now, if not more.
Still, no one knows. We could stop growing for 5 years or continue classes for the next year straight. Either way, anyone who gets hired should consider themselves lucky. As CHPR stated, 5,500 resumes. Combine that with at least 200 pilots walking in stuff for their friends and only 24 spots. Good luck.
