You are right and this goes to an important point. Someone at BA believes that all they need to do is send us some cut and pasted apologetic language (your email above is pretty much the same as ones I've received), but what they seem to lack is the awareness that this type of email is arguably worse than nothing.

However I would never threaten to go to another airline. I earn Gold every year and as such I just want BA to be a better airline and want the staff to do the best they can at their job. Which for the most part they do. It's management that seems to have lost the plot.
