Could this be too late in the day to alter the rotations? Most likely maybe an extra rotation on the Dash8 which is just GLA-CWL-GLA. Whether there are aircraft available for this remains to be seen.
What about the possibility of GLA-CWL-AMS as the extra rotation? Could kill two birds with one stone and should work as an all rounder. Or even GLA-CWL-NQY.
Even though i would like to see the E95 at Cardiff on the scheduled basis i don't think we will unless Flybe base at CWL.
