Starting pay at Ameriflight is $1,700/mo on the Lance with pay raises beginning after 3 months.  Upgrade into the Chieftain depends on your base.  It seems to be the lowest in Oakland 
( approx. 2 months) and highest in Phoenix..(currently at 4-5 months).  Upgrade into the Turboprops can happen in under 12 months if you are willing to relocate somewhere such as Billings, MT.  
Classes are being ran fairly often, atleast one a month, possibly more.  One class is finishing up this week, and I'm sure there will be atleast one more this month and more in June.
Hope this helps!
