British Regional had it perfect at CWL.....small turboprop aircraft operating to a wide range of destinations.....CWL is obviously suited to good frequencies with smaller aircraft......BAe J41 be perfect and could operate to CDG, BRU, GLA, ORK, JER & GCI to name a few.
J41, D38 & AT4 aircraft be spot on.....BA Regional did 3 CDG flights a day along with 2 BRU flights a day with J41's and it worked well for them.....far more suitable than a A319 or 737 ex CWL !!!
