EXT, BRS CWL all had TCX/MT IT flights - I gather CWL was summer only - not sure if EXT was the same, and EXT had no based TCK a/c there so I have been told)
Whether TUI/TOM will pick up the TCX slack at these airports remains to be seen, but TUI have used 3rd party airlines such as Alba Star Freebird and Norwegian to fly their packages for a few years to some destinations.
