I could only see the Q400 on SYY/LSI/KOI to the central belt. It's too big for all of the other locations to make money on.
flyBE should have access to lots of sales data so will be well placed to work out which routes would work if they operated them in their own right and make money on them.
Stranger things have happened in the world of flyBE! I wouldn't rule anything in our out.
