I think BE will stay on the route for extra operational days providing more choice for CWL passengers.
Not sure when the BE Summer 2017 schedule will be released but i bet that it's pretty soon. Seen elsewhere that VY have secured an additional 4x A320 for next Summer, I wonder whether this will be aimed at fixing the problems that they've had this Summer, or expanding at BCN/ALC. If the latter i'd expect more CWL rotations to come our way.
