BRS/ABZ was once operated by BA as a transit flight through NCL on a DH8C-300. Their used to be about 20 pax on the flight flying on to ABZ on a regular basis.
When BA pulled the route and then not to long after pulled out of the NCL route because of EZY's desire to operate it on a B73A most of the pax travelled BRS/GLA then connected on to the GLA/ABZ. I think that introducing this direct service will be a big coupe for Eastern as well as ABZ and BRS.
Good Luck to them and hope they introduce more domestic routes in the near future.
