do u mean there is a problem with pilots wishing to re-locate to Cardiff/Wales?
The EDI route seems to be doing incredibly well. Its as if they are cutting and handing over routes that attract high costs i.e Paris CDG etc.
The cardiff market is a tricky one though. Not too affluent (im being serious here) and so routes to places like Nice, Biaritz, Milan, Geneva and Scandinavia may not work.
However, Bucket and spade and Spanish/southern med routes are under-served!
