Since a lot of the CLT trips with DCA flying have DCA overnights, it's likely new trips out of the DCA base will contain more one, two and three day trips rather than the four day majority we are stuck with in CLT. DCA flying has a greater ratio of aircraft round trips to aircraft outstation RONs than CLT has. CLT flying has too many aircraft outstation RONs, causing the trips to have lower credit and be almost all four days.
