Carcassone?? get real. It's a short runway with predominatley a circling approach. Small apron with no hangar or large a/c maintenance facilities. Is the home of an aerobatic school. It is a flying club airfield. Blackpool not dissimilar.
Strange no-one has made mention of Eindhoven or Niederhein. Both have had energetic visits from RYR management recently. The former has a new terminal it needs using, and the latter has lost its home based airline. Geographically they are in great locations and both have a large populous capture area. With CRL and these two, RYR would have a strong prescence across a central swath of Europe.
