When I used to work with BE at EDI it would quite often be the case that the same aircraft would leave EDI in the morning, fly to BHX, BHD, MAN or SOU and then just dot back and forward between those two airports all day. Some of the less frequent routes like NWI, MSE for CWL for example may see an aircraft go to CWL in the morning, fly back to EDI, then go down to MSE, back to EDI, then CWL before returning to EDI, maybe doing another MSE before retiring to EDI for the night.
There would be variations for seasonal or non daily routes for example BE had weekly charters to IBZ, INN or PMI and a few services a week to NOC in summer time.
