Happened to me a week or so ago and cleared itself the following day. I did check that the price had not gone up as I was keen to secure the flights and lose the deposit if push came to shove and was very surprised to see that the flights had gone down by about £15 from £166 to £151. The online help did suggest that BA would automatically reprice the flights at the lower rate but BA.com did not play ball. I phoned in the end and they asked me to book again at the lower price & refunded me the £10 holding fee. The old booking died and disappeared from the system.
