I currently do King Air contract work on a 200 out of Newburgh, NY (KSWF). Day rate for me is $500.00 as the PIC, even if I am flying in the right seat for the owner/pilot. When the owner wants to sit in the back with his family, we bring an SIC, and the rate is $300.00 for the co-pilot. I do the same on an E90 out of Trenton, NJ (KTTN), and I still get $500.00. Typed in a 350, and those rates are $600.00/$400.00. Hope that helps.
