Never heard of the mighty 700 carrying out any form of route type training before. Usually only base training, management shuttle or real emergency commercial duties. Maybe some management types keeping current. Most base training done at EMA but EMA is busy and CWL could be a good fit for training.
Lots of new bases announced again and lots of places being looked at. Lots of new aircraft coming. Have it on very good authority there is more in the pipeline for CWL but no timescale. Depends on other opportunities and company concerned about EU situation and UK. One thing that I know for sure though is that there is at least one CWL sympathiser high up in FR.
