Seems bizarre that EZY don't do that, I suppose BRS would gave something to say about it & most probably a clause in their contract but a weekly BRS-GVA-CWL-GVA-BRS would be great in the quieter winter months.
Hopefully some increase in long haul would be good, as I said before Air Canada Rouge would be well suited, Canada has been served & well used for years ex CWL
