BA back at Cardiff? Well, past experience has taught me never to try and double-guess the people at Waterworld, but it would fly in the face of all logic if BA are winding up their regional operation just about everywhere else, only to, in parallel, reopen routes to someone else's low-cost hub.
I have a feeling this rumour can trace its routes back to wikipedia - someone suggested on there that BA were looking to run a 777 service to JFK from CWL. The danger of wikipedia is that anyone can write it, even the terminally clueless....!
It was removed very quickly, but this one seems to be doing the rounds... fuelled no doubt as well by the peripatetic A320 at Cardiff recently...
I would guess flybe are having a pop on the BHD to see what baby do, rather than to pre-empt a BA re-appearance, à la Banquo's ghost.
