Wait on that until you return from your trip and file a claim. You will receive pushback from BA, but it ought to be a fairly simple affair before CEDR.
This is a change with more than 14 days notice, so does EC261 apply here? BA will, obviously be offering a partial refund but I didn't think they needed to agree to the 75% formula?
