Not trying to get involved in the fray but the number of flights doesn't matter. What matters is the amount of seats. Frequency is going away for fewer flights with more seats. 8 flights a day in a 145 can easily be replaced by 5 175/900's. So that means fewer pilots overall needed. Hell, you throw in 1 MD-80/A320 flight and you can decrease the number of flights by 2.

Once the 50 seaters and smaller are gone there will be fewer pilots needed to move the same amount of passengers. So really they would only need to be able to replace 1400 flights with 921 (using 50 seats as an average). With Skywest/Expressjet and Air Wisconsin having a great deal of 50 seaters that are going to be exchanged for fewer 175/900's there will be plenty of pilots available to fly those flights. Not to mention the overlap that you will see go away as hubs are shrinked or shutdown.
