bcn_boy,
It's not only long haul, it's non EU, not sure how the likes of Norway and Switzerland fair on this one, but it might also impact upon BRS's KLM, Air France etc. long haul feeder services where if the punter is connecting in less than 24 hours then 'rip off' APD applies.
However ... as has been said many a time, BRS and CWL have two totally different catchments and with regards to BHX ... are the likes of KLM, Air France, Sabena, Swiss, SAS, Lufthansa etc. likely to relocate their services from BHX to CWL? ... Never in a hundred years!
