There was an apology of some sort though. The point I'm making, I suppose, is, are we becoming so compensation-orientated nowadays that every bit of inconvenience requires a compensation, even when the other party apologises?

This is not to take away from the fact that the OP was inconvenienced and that BA was in the wrong not to have provided a promised item.

In my experience when BA look at the complaint and they feel that it is bad enough to warrant 'making it up to you', then they would throw Avios at you.

I also suspect it depends on the complaint/number of flight ratio too, unless it's a standard item like IFE failure reported by crew.
