IJ,
Exactly as I posted - I doubt they will run with punters' money, but there are other costs involved with making a travel booking that a flight canx refund would not cover.
There is also a small question of car hire - never good value with locos anyway imho, but if baby were to cancel your flight, and you've booked a hire car, their deal is with an agency (CarTrawler), who then contract with the rental co. Who would be responsible for the refund?
BA used to own go, and baconnect, I don't think they are in the business of running locost. I don't care who makes my chocolate bar, I have never wanted a refund on one!
