Prairie Air Service
Hi,
just finished my training here - if you look for the biggest bank for the buck, there is a reason why AF Colonels that command B-2s, B-1Bs, KC-135s etc. plus half the Singapore Air Force do it here.
If you don't need a typerating, I guess this is the most affordable way. If you need a typerating then I am the wrong guy to answer where you could get it any cheaper.
Good luck, since I am at 290 hrs I unfortunately don't have the luxury of asking your question yet ;-),
