I think everybody has overstated the awareness Joe Public has of the industry. If they really did turn away from particular airlines with perceived 'dodgy' reputations then I'm sure there would be many more empty seats on a number of carriers worldwide. I doubt there is any lasting harm done at all to the TCX reputation.
However, now the public can add reckless stunt pilot to their stereotype of us as randy old drunks. It's the pilots who have the rep, not the airlines.
