I my feeling is that ABZ is a route that is definetly being considered at flybe and think that it would probably work better with CWL-MAN-ABZ, The other way this may work is to make GLA a direct service (same as they did with the BHD), and make the route an ABZ-CWL-CDG-CWL-ABZ.
When Flybe to have a base at CWL and become the largest carrier at the airpoirt by 2011 as planned we shall hopefully see more domestic routes along with a few German ones.
