I don't think you can blame the Echo for taking an advert from Ryanair.
Ryanair are paying them for the privelage of running the advert you know and Trinity Mirror aren't doing it out of the goodness of their heart (they need the money by all accounts anyway).
It would probably be more constructive if someone could find out the management at Cardiff Wales Airport aren't running an advert in the Echo to push the products they have on offer.
