I definitely don't believe this one !
FlyBE are stretched to breaking point as it is ... there are cancelling flights all over the route network.
Before the BACX purchase, they were looking forward to finally having 2 types (EMB195 and DHC8). MOL and others have proved that to be an efficient low cost carrier, you need as few aircraft types as possible (preferably 1).
FlyBE are now back up to 5 aircraft types, and if they were to go for Logan, they'd be increasing that yet further on unprofitable routes.
