Perhaps BEE have still to announce further flying for the aircraft?
Maybe or tweek the current schedule. The ER4 could operate the existing SOU route, freeing up a DH4. Posted this as a possible tweek to the schedule on Newcastle thread:
BE6xxx NCL 07:00 SOU 08:15
BE6xxx SOU 08:50 NCL 10:05
BE6881 NCL 11:00 STN 12:15
BE6882 STN 12:45 NCL 14:00
BE6xxx NCL 14:45 SOU 16:00
BE6xxx SOU 16:30 NCL 17:45
BE6xxx NCL 18:15 SOU 19:30
BE6xxx SOU 20:00 NCL 21:15
Guess we will just have to wait and see what BM decide to do
