I think this is the last list of all today's (Sunday 10 December 2017) cancellations, I doubt there will be many more, if any. Still, it's 176 cancellations out of about 330 LHR flights. 4 cancellations for LGW plus LCY. Tomorrow will also be bad, BA have aircraft and equipment scattered all over Europe now.
