Are the “eco loonies” Ryanair has spoken of in the past finally taking over the asylum? This report in the Guardian suggests that, despite its earlier denials, Ryanair is now ready to accept that some of the decline in ticket sales is being driven by growing concern among travellers about aviation’s impact on the environment.

Howard Millar, Ryanair deputy chief executive, said he was “concerned” about the negative publicity gathering around the airline sector and admitted demand for flights was being impacted “at the edges”.

“I am concerned that there is a continuing media campaign and the concern is that people might say ‘maybe I will not fly on holiday and maybe I will make a different choice,'” he said.
