I wouldn't worry Ayline, Flybe have bigger fish to fry and would not be interested in ATR's, Dorniers, Trislanders or Jetsteams
Should BCI not think about getting their business model right before merging with another airline. You need to ensure you have a good customer base and from what I have been hearing from BCI regulars is that they are getting fed up with the changes being implemented (schedule and business model.)
