I realise you're not talking here in an official capacity for BA - and I do understand that you had a frustrating time watching flights leaving with empty seats, leaving people behind who wanted to fill them. People should have the courtesy to contact BA when they've checked in and then changed their plans.
However I think you'll find that a significant number of people who did this were UNABLE to contact BA because they COULDN'T get through on the telephone and, like me, gave up in frustration.
What I'm saying is - the company could be doing some simple things to help its frontline staff deal with problems like yesterday's fog more successfully. Updating its website properly and allocating enough staff to answer calls from its customers would be a start.
Anyway. It's Christmas now - hope you have a good one.
