Sadly statistics also show that BA don't need to give a toss.

Cruz did his best to destroy the brand, and yet sufficient lemmings continued to fly BA, either due to misguided blind loyalty or mere convenience.

BA also have a monopoly at Heathrow and so have an almost guaranteed pipeline of willing victims.

So even if someone tells 9 people and those 10 people vow to never fly BA again, they will be replaced with alternative self-loading cattle in no time, probably even before the unhappy guy has finished emailing the 9th person.

That's the problem with BA. They can afford to be complacent. We can but hope that one day their luck will run out, but for now, it is what it is.
