Updating my earlier post...aircraft withdrawn from use in Phoenix are N907FR (Mel the Mule Deer) and N915FR (Mustang Sally). Both are being sold at VTB Leasing for eventual lease to Rossiya Russian Airlines.
N901FR, N903FR, N909FR, N917FR have already left for VTB Leasing. N913FR and N916FR are still in service but will be sold to VTB shortly.
