No idea accurate the stats are but this site (
https://www.anna.aero/2020/03/05/fly...top-30-routes/) suggests only 168 pax per day were flying SOU - MAN. Six 78 seat Dash flights a day shows how much capacity Flybe 1.0 were providing with not many takers. 35% load factor!?
It would be interesting to see if a seats available vs pax travelled analysis exists.
