Air Wisconsin was 6 weeks of ATP/Indic/Systems, a week sit at home, then a week of CPT, a week at home, and 2-3 weeks of sims with some breaks in between depending on your progression. We had guys done with the type ride in a little as 8 weeks from starting class (already had ATP, no additional sims required) to as long as 12 weeks (no ATP to start, additional sim periods required).
After your type ride and depending on the airline, 2-4 trips of IOE (2-4 more weeks) before you are on the line.
