The forthcoming abolition of the bridge toll will remove one of the disincentives for SW England residents of using CWL. However, I am unconvinced that CWL will be a major player when BHX is only 45 miles further distant, with a much wider range of choices of connecting airlines and daily rotations. If the connections via the QR flight from CWL fit, perhaps, but generally, no. Turkish at BRS would be lovely but it is unlikely to happen because of BHX.
