Is All Publicity Good Publicity?

As the 'legitmate' rival of 'illegitimate' Ryanair, I would not necessarily look with disdain on an Aer Lingus sale. However, I got a spam mail about special offers today and felt an immediate sense of recoil. Analysing my feeling I found the reason to be obvious enough; the recent fiasco with the so-called five euro seats was still fresh in my mind. Is it just me? I get the feeling Aer Lingus have done themselves a lot more harm than they realise with their behaviour over that stunt. I didn't go to their site.
