Noticed that FLYBE are having continuing problems managing the schedules since taking on the Connect business from BA. Seems the current policy is cancel flights with low SLF loads, and take it in turn as which flights, to which airports, they cancel when staff shortages occur.
Suspect they have a rota system, until things get back to normal.
