Has anyone who booked a flight during the above dates, and since flown on those bookings been able to do an online checkin to see if the error has been corrected by BA, or is it still not possible to check in online? By now they should have found and corrected the problem, or is it too complex to correct? Means lots of extra time at the airport if we can't check in online or not even use the kiosks at LHR, but instead have to join the already long lines.
